Hereinafter, the present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0027] See Figures 1 to 10 , the figure shows the preferred structure of the construction auxiliary device in this embodiment. As shown in the figure, the construction auxiliary device includes: a base 1, a support cylinder 2, a support device 3, and a lamp 4. Among them, the base 1 is movable to drive the construction auxiliary device to move to the required position. The support cylinder 2 is telescopable along its height direction ( Figure 1 the direction from top to bottom as shown), the bottom of the support cylinder 2 ( Figure 1 the lower part as shown) is arranged on the base 1, and the support cylinder 2 is perpendicular to the base 1. The support device 3 is arranged on the top of the support cylinder 2 ( Figure 1 the upper part as shown) with adjustable circumferential position, that is, the support device 3 is arranged on the top of the support cylinder 2 and its position in the circumferential direction is adjustable, and the lamp 4 is arranged on the support device 3. In this way, the position of the lamp 4 in the circumferential direction can be adjusted, so as to realize the adjustment of the irradiation position of the lamp 4.

[0028] The support device 3 can be tilted by itself to adjust the irradiation angle of the lamp 4.

[0029] It can be seen that in this embodiment, the bottom of the telescopic support cylinder 2 is arranged on the base 1, and the top of the support cylinder 2 is provided with a lamp 4. The height of the lamp 4 can be adjusted by the self-telescoping of the support cylinder 2. Moreover, the position of the support device 3 at the top of the support cylinder 2 is adjustable circumferentially, so that the position of the lamp 4 can be adjusted circumferentially, realizing the adjustment of the irradiation position of the lamp 4. And the support device 3 itself can be tilted, realizing the adjustment of the irradiation angle of the lamp 4. In this way, the height, irradiation position and irradiation angle of the lamp 4 can be adjusted according to actual needs, realizing the adjustment of the position of the lamp 4, making the lighting of the lamp 4 better meet the construction requirements, and being able to better assist in construction, solving the problem in the prior art that the lamp body is fixed on the wall or pole and the position of the lamp body cannot be adjusted. And the base 1 is movable, driving the movement of the lamp 4, and can be moved to the required position according to needs, meeting the lighting requirements of construction, and the operation is simple and convenient.

[0030] See Figures 1 to 3 , in the above embodiment, the support cylinder 2 includes: a fixed cylinder body 21, a movable cylinder body 22 and a first driving mechanism 23. Among them, the inside of the fixed cylinder body 21 is hollow, and the bottom of the fixed cylinder body 21 ( Figure 2 the lower part shown) is vertically arranged on the base 1, and the top of the fixed cylinder body 21 ( Figure 2 the upper part shown) is provided with a through hole.

[0031] The inside of the movable cylinder body 22 is hollow, and the top of the movable cylinder body 22 ( Figure 2 the upper part shown) is connected to the support device 3 in a position-adjustable manner. The movable cylinder body 22 is movably inserted through the through hole, and the bottom of the movable cylinder body 22 ( Figure 2 the lower part shown) is placed inside the fixed cylinder body 21.

[0032] The first driving mechanism 23 is arranged in the fixed cylinder body 21, and the first driving mechanism 23 is connected to the part of the movable cylinder body 22 placed inside the fixed cylinder body 21. The first driving mechanism 23 is used to drive the movable cylinder body 22 to move from the through hole to the outside of the fixed cylinder body 21, so that the length of the support cylinder 2 is extended, and to drive the movable cylinder body 22 to move from the through hole to the inside of the fixed cylinder body 21, so that the length of the support cylinder 2 is shortened.

[0033] The first driving mechanism 23 includes: a connecting rod 231 and at least one driving body 232. Among them, the first end of the connecting rod 231 is placed outside the fixed cylinder 21. The connecting rod 231 is rotatably inserted through the side wall of the fixed cylinder 21, and the second end of the connecting rod 231 is placed inside the fixed cylinder 21. Each driving body 232 is spacedly arranged on the rod body of the connecting rod 231 placed inside the fixed cylinder 21, and each driving body 232 is connected to the moving cylinder 22. Specifically, each driving body 232 can be a rubber friction wheel or a gear. Embedding grooves extending along the height direction of the moving cylinder 22 are formed on the side wall of the moving cylinder 22. The positions of the embedding grooves correspond to the positions of the driving bodies 232 one by one. A friction pad cooperating with the rubber friction wheel or a tooth groove cooperating with the gear is arranged in each embedding groove. In this way, the rotation of the connecting rod 231 drives the rotation of each driving body 232, and each driving body 232 drives the moving cylinder 22 to move upward or downward (relative to Figure 2 ), realizing the elongation or shortening of the support cylinder 2. During specific implementation, the length of the embedding groove can be determined according to the actual situation, and this embodiment does not make any restrictions on this.

[0034] During specific implementation, a first self-locking rotary handle 233 is arranged on the outer wall of the fixed cylinder 21. The first self-locking rotary handle 233 is fixedly connected to the first end of the connecting rod 231. By the staff rotating the first self-locking rotary handle 233, the rotation of the connecting rod 231 is driven, and further the movement of the moving cylinder 22 is driven.

[0035] It can be seen that in this embodiment, the support cylinder 2 drives the moving cylinder 22 to move out of or into the fixed cylinder 21 through the first driving mechanism 23, so that the support cylinder 2 can be telescopic by itself. This structure is simple and easy to implement.

[0036] See Figure 1 、 Figures 3 to 8 In the above-mentioned embodiment, the support device 3 includes: a rotating plate 31, a support column 32, an inclined plate 33 and a second driving mechanism 34. Among them, the rotating plate 31 is rotatably arranged on the top of the moving cylinder 22. Specifically, a rotating ring 35 is arranged on the surface of the rotating plate 31 facing the moving cylinder 22, and the rotating ring 35 is rotatably connected to the top of the moving cylinder 22.

[0037] The bottom of the support column 32 is arranged at a position close to the edge of the rotating plate 31. Specifically, the support column 32 is perpendicular to and fixed to the rotating plate 31, and the position of the support column 32 on the rotating plate 31 is close to the edge of the rotating plate 31.

[0038] The inclined plate 33 is rotatably arranged on the top of the support column 32, and the inclined plate 33 is along the height direction of the support column 32 ( Figure 3It rotates up and down in the vertical direction (the direction from top to bottom as shown), wherein the height direction of the support column 32 is consistent with the height direction of the moving cylinder 22. The lamp 4 is arranged on one side of the inclined plate 33, and the rotation of the inclined plate 33 enables the lamp 4 to be inclined, realizing the adjustment of the irradiation angle of the lamp 4.

[0039] The second driving mechanism 34 is connected to both the rotating plate 31 and the inclined plate 33. The second driving mechanism 34 drives the rotating plate 31 to rotate to drive the lamp 4 to rotate, so that the lamp 4 adjusts the irradiation position in the circumferential direction. Moreover, the second driving mechanism 34 drives the inclined plate 33 to rotate, so that the lamp 4 is inclined, realizing the adjustment of the irradiation angle of the lamp 4.

[0040] See Figures 3 to 8 , the second driving mechanism 34 includes: a transmission rod 341, a driving assembly 342, a transmission mechanism 343, and an auxiliary mechanism 344. Among them, the driving assembly 342 is arranged inside the moving cylinder 22, and the driving assembly 342 is connected to the transmission rod 341, and the driving assembly 342 is used to drive the transmission rod 341 to rotate.

[0041] The bottom surface of the rotating plate 31 (i.e., the surface of the rotating plate 31 facing the moving cylinder 22) is rotatably connected to the top of the moving cylinder 22. Specifically, a rotating ring 35 is arranged on the bottom surface of the rotating plate 31. Moreover, the rotating plate 31 is provided with a through hole, and the through hole is located at the central position of the rotating plate 31.

[0042] The transmission rod 341 is rotatably passed through the top of the moving cylinder 22 and the through hole in sequence, and the transmission rod 341 is connected to the inclined plate 33 through the transmission mechanism 343. Specifically, the bottom of the transmission rod 341 is placed inside the moving cylinder 22. After the transmission rod 341 passes through the top of the moving cylinder 22 and the through hole of the rotating plate 31, it is connected to the transmission mechanism 343. Since the support column 32 is arranged between the rotating plate 31 and the inclined plate 33, the transmission mechanism 343 is arranged in the space between the rotating plate 31 and the inclined plate 33, and the transmission mechanism 343 is connected to the inclined plate 33.

[0043] The auxiliary mechanism 344 is arranged between the rotating plate 31 and the transmission rod 341. The auxiliary mechanism 344 is used to drive the rotating plate 31 to rotate when the transmission rod 341 rotates. The rotating plate 31 drives the lamp 4 to rotate through the support column 32 and the inclined plate 33, and after the rotating plate 31 rotates to the required position, the auxiliary mechanism 344 limits the rotating plate 31 so that the rotating plate 31 no longer rotates, then the lamp 4 also no longer rotates. At the same time, the auxiliary mechanism 344 controls the separation of the transmission rod 341 from the rotating plate 31.

[0044] The transmission mechanism 343 is used to ensure that after the transmission rod 341 is separated from the rotating plate 31, when the transmission rod 341 rotates, the rotation of the transmission rod 341 no longer drives the rotation of the rotating plate 31, but instead drives the rotation of the inclined plate 33.

[0045] See Figure 3 , the driving assembly 342 includes: a first rotating rod 3421, a fixing plate 3422, a driving rod 3423, a telescopic cylinder 3424 and a connecting plate. Among them, the bottom of the moving cylinder body 22 is open. The fixing plate 3422 is horizontally arranged on the inner wall of the fixed cylinder body 21, so the fixing plate 3422 is fixed to the fixed cylinder body 21, and the bottom of the moving cylinder body 22 is placed above the fixing plate 3422 (relative to Figure 3 ).

[0046] The first end of the first rotating rod 3421 is placed outside the fixed cylinder body 21. The first rotating rod 3421 is rotatably inserted through the side wall of the fixed cylinder body 21. Part of the rod body and the second end of the first rotating rod 3421 are both placed inside the fixed cylinder body 21 and below the fixing plate 3422. Specifically, a second self-locking rotary handle 3425 is arranged on the outer wall of the fixed cylinder body 21. The second self-locking rotary handle 3425 is fixedly connected to the first end of the first rotating rod 3421, and the staff rotates the second self-locking rotary handle 3425 to drive the rotation of the first rotating rod 3421.

[0047] The bottom of the driving rod 3423 ( Figure 3 the lower part shown) is meshed and connected with the first rotating rod 3421. Specifically, the first rotating rod 3421 is horizontally arranged inside the fixed cylinder body 21, the driving rod 3423 is vertically arranged inside the fixed cylinder body 21, bevel gears are arranged at the bottom of both the first rotating rod 3421 and the driving rod 3423, and the bottom of the first rotating rod 3421 and the driving rod 3423 are connected by bevel gears, so the rotation of the first rotating rod 3421 drives the rotation of the driving rod 3423. The driving rod 3423 is rotatably inserted through the fixing plate 3422, and the top of the driving rod 3423 ( Figure 3 the upper part shown) is connected to the bottom of the telescopic cylinder 3424 ( Figure 3 the lower part shown). Specifically, the telescopic cylinder 3424 is placed inside the moving cylinder body 22, and the telescopic cylinder 3424 is arranged along the height direction of the moving cylinder body 22 inside the moving cylinder body 22. The telescopic cylinder 3424 can be telescoped along its own height direction, and the height direction of the telescopic cylinder 3424 is consistent with the height direction of the moving cylinder body 22. Preferably, the cross-section of the telescopic cylinder 3424 is rectangular.

[0048] The connecting plate is horizontally arranged inside the moving cylinder body 22, and the connecting plate is parallel to the fixing plate 3422.

[0049] The bottom of the transmission rod 341 ( Figure 3The lower part shown) is connected to the top of the telescopic cylinder 3424 ( Figure 3 The upper part shown), the transmission rod 341 is rotatably passed through the connecting plate, and the top of the transmission rod 341 ( Figure 3 The upper part shown) is rotatably passed through the top of the moving cylinder body 22 and the through hole of the rotating plate 31 in sequence, and the top of the transmission rod 341 is connected to the transmission mechanism 343.

[0050] The rotation of the second self-locking rotary handle 3425 drives the rotation of the first rotating rod 3421, which in turn drives the rotation of the driving rod 3423. The rotation of the driving rod 3423 drives the rotation of the telescopic cylinder 3424. The telescopic cylinder 3424 drives the rotation of the transmission rod 341, realizing the rotation of the transmission rod 341. When the moving cylinder body 22 moves outwards from the fixed cylinder body 21 to the outside of the fixed cylinder body 21, the movement of the moving cylinder body 22 drives the movement of the connecting plate, the connecting plate drives the movement of the transmission rod 341, and then drives the telescopic cylinder 3424 to extend along with the moving cylinder body 22. Correspondingly, when the moving cylinder body 22 moves into the fixed cylinder body 21, the telescopic cylinder 3424 contracts along with the moving cylinder body 22.

[0051] During specific implementation, the fixing plate 3422 is provided with an opening corresponding to the driving rod 3423, the driving rod 3423 is provided with an annular embedding groove, and a bearing or a rotating shaft is arranged in the annular embedding groove, so that the driving rod 3423 and the fixing plate 3422 can rotate relative to each other. The connecting plate is also provided with an opening corresponding to the transmission rod 341, the transmission rod 341 is also provided with an annular embedding groove, and a bearing or a rotating shaft is arranged in the annular embedding groove, so that the transmission rod 341 and the connecting plate can rotate relative to each other.

[0052] Refer to Figure 3 and Figure 4 , the transmission mechanism 343 includes: a slider 3431, a threaded cylinder 3432, and a threaded rod 3433. Among them, a guide groove 331 is provided on the surface of the inclined plate 33 facing the rotating plate 31. The slider 3431 is slidably arranged in the guide groove 331, and the threaded cylinder 3432 is rotatably connected to the slider 3431. The top of the transmission rod 341 is connected to the threaded rod 3433, and the threaded rod 3433 is screwed with the threaded cylinder 3432. The rotation of the transmission rod 341 drives the rotation of the threaded rod 3433. Since the threaded rod 3433 and the threaded cylinder 3432 are screwed together, the rotation of the threaded rod 3433 drives the movement of the threaded cylinder 3432, so that the slider 3431 slides in the guide groove 331, and the sliding of the slider 3431 pushes the inclined plate 33 to rotate, realizing the adjustment of the irradiation angle of the lamp 4.

[0053] In specific implementation, the guiding groove 331 can be a dovetail groove or a T-shaped groove, so that when the slider 3431 slides in the guiding groove 331, the slider 3431 can be limited to prevent it from falling when sliding.

[0054] See Figure 3 , Figures 5 to 8 , the auxiliary mechanism 344 includes: a control ring 3441, a plurality of extrusion blocks 3442, a plurality of elastic members 3443, a plurality of elastic telescopic rods, an annular extrusion body 3444 and a pushing structure. Among them, an annular groove 311 is formed on the bottom surface of the rotating plate 31, and the annular groove 311 is recessed towards the top surface of the rotating plate 31, and a through hole is disposed at the annular center of the annular groove 311.

[0055] A plurality of sliding grooves 312 are formed on one side of the annular groove 311 facing the transmission rod 341. Specifically, the annular groove 311 has an annular inner wall, an annular outer wall and an annular bottom wall. The annular bottom wall is clamped between the annular inner wall and the annular outer wall. The annular inner wall is closer to the through hole of the rotating plate 31 than the annular outer wall. A plurality of sliding grooves 312 are formed at intervals in the circumferential direction on the annular inner wall, and each sliding groove 312 extends towards the through hole until each sliding groove 312 communicates with the through hole. At this time, each sliding groove 312 communicates with both the annular groove 311 and the through hole.

[0056] Each extrusion block 3442 corresponds to each sliding groove 312 one by one. Each extrusion block 3442 is slidably disposed in the corresponding sliding groove 312. One end of each extrusion block 3442 is meshed and connected with the transmission rod 341, and the other end of each extrusion block 3442 is connected with the side wall of the annular groove 311 through an elastic member 3443. Specifically, each elastic member 3443 corresponds to each extrusion block 3442 one by one. The other end of each extrusion block 3442 is connected to one end of the corresponding elastic member 3443, and the other end of the elastic member 3443 is connected to the annular outer wall. Each elastic member 3443 can be a spring.

[0057] In specific implementation, the transmission rod 341 is provided with a friction rubber wheel or a gear, and the end of each extrusion block 3442 connected to the transmission rod 341 is provided with a friction pad cooperating with the friction rubber wheel or a tip cooperating with the gear, so that when the transmission rod 341 rotates, it drives the extrusion block 3442 to rotate through meshing with the extrusion block 3442, and then drives the rotating plate 31 to rotate.

[0058] In specific implementation, each sliding groove 312 can be a dovetail groove or a T-shaped groove, so that when the extrusion block 3442 slides in the sliding groove 312, the extrusion block 3442 can be limited to prevent it from falling when sliding.

[0059] On each side of each extrusion block 3442 facing the moving cylinder body 22, a notch 34421 with a triangular cross-section is formed. Specifically, the cross-section of the notch 34421 is a right triangle. One of the right sides of the notch 34421 is the opening of the notch 34421, and the other right side and the hypotenuse form the notch 34421.

[0060] The control ring 3441 is arranged in the annular groove 311 through each elastic telescopic rod. That is, a plurality of elastic telescopic rods are arranged at intervals in the annular groove 311. The control ring 3441 is connected to each elastic telescopic rod, so that the control ring 3441 can be elastically telescopic in the annular groove 311. By arranging the elastic telescopic rod, elastic force can be provided for the control ring 3441 and guiding can be carried out during the movement of the control ring 3441.

[0061] The cross-section of the annular extrusion body 3444 is triangular. Moreover, the annular extrusion body 3444 is arranged on the side of the control ring 3441 facing the rotating plate 31. That is, the annular extrusion body 3444 is arranged on the top surface of the control ring 3441, and the bottom surface of the control ring 3441 faces the moving cylinder body 22. The annular extrusion body 3444 is inserted into the notch 34421 of each extrusion block 3442, and the inclined surface of the annular extrusion body 3444 is matched with the inclined surface of the notch 34421. Specifically, the cross-sectional shape of the annular extrusion body 3444 matches the cross-sectional shape of the notch 34421. The cross-section of the annular extrusion body 3444 is also a right triangle. One of the right sides of the annular extrusion body 3444 is connected to the top surface of the control ring 3441. The other right side of the annular extrusion body 3444 is in contact with the right side of the notch 34421, and the inclined surface of the annular extrusion body 3444 is in contact with the inclined surface of the notch 34421.

[0062] During specific implementation, since the control ring 3441 is connected to the bottom wall of the annular groove 311 through a plurality of elastic telescopic rods, when the control ring 3441 is in a free state, the control ring 3441 protrudes from the bottom surface of the rotating plate 31. In order to ensure the rotational connection between the rotating plate 31 and the moving cylinder body 22, the height of the rotating ring 35 on the bottom surface of the rotating plate 31 is greater than or equal to the distance between the bottom surface of the control ring 3441 and the top surface of the rotating plate 31 when the control ring 3441 is in a free state. That is, the bottom surface of the rotating ring 35 is rotatably connected to the top of the moving cylinder body 22. The bottom surface of the rotating ring 35 is placed below the bottom surface of the control ring 3441 in a free state or the two bottom surfaces are flush, so that the rotating ring 35 encloses the control ring 3441 inside.

[0063] The pushing mechanism is arranged on the moving cylinder body 22, and the pushing mechanism cooperates with the control ring 3441. The pushing mechanism is used to push the control ring 3441 to move into the annular groove 311. The annular extrusion body 3444 on the top surface of the control ring 3441 moves into the notch 34421 of each extrusion block 3442, so that each extrusion block 3442 moves towards the annular outer wall of the annular groove 311. Each extrusion block 3442 extrudes each elastic member 3443. After the annular extrusion body 3444 is completely inserted into each notch 34421, the transmission rod 341 is separated from each extrusion block 3442. At this time, the rotation of the transmission rod 341 is no longer associated with each extrusion block 3442. Due to the restriction of the control ring 3441 on each extrusion block 3442, the control ring 3441 keeps the rotating plate 31 stationary. Since the transmission rod 341 is separated from each extrusion block 3442, when the transmission rod 341 rotates under the drive assembly 342, the transmission rod 341 drives the threaded rod 3433 to rotate, and then drives the movement of the threaded cylinder 3432, so as to make the inclined plate 33 rotate.

[0064] The pushing mechanism includes: a plurality of pushing units. Among them, an operation port 221 is opened at the top of the moving cylinder body 22, and the operation port 221 is provided for the transmission rod 341 to rotatably pass through. Specifically, the diameter of the operation port 221 is larger than the outer diameter of the transmission rod 341.

[0065] Each pushing unit is arranged at the operation port 221 at intervals, and each pushing unit corresponds to the control ring 3441, and each pushing unit pushes the control ring 3441 to move into the annular groove 311.

[0066] The inner wall of the operation port 221 of the moving cylinder body 22 is provided with a sliding groove 222 corresponding to each pushing unit. Then, each sliding groove 222 corresponds to each pushing unit one by one, and each sliding groove 222 extends along the height direction of the moving cylinder body 22. And, a recessed accommodating cavity 223 is opened at the bottom wall of each sliding groove 222, and the accommodating cavity 223 is communicated with the corresponding sliding groove 222.

[0067] Each pushing unit includes: an L-shaped push rod 3445, a lever 3446 and a pull rope 3447. Among them, the first end of the push rod 3445 is slidably arranged in the sliding groove 222 along the height direction of the moving cylinder body 22, and the second end of the push rod 3445 is inserted into the accommodating cavity 223. Specifically, the first end of the push rod 3445 is arranged along the height direction of the moving cylinder body 22, and the second end of the push rod 3445 is perpendicular to the height direction of the moving cylinder body 22. And, the end of the first end of the push rod 3445 corresponds to the control ring 3441.

[0068] The toggle lever 3446 is rotatably arranged in the accommodation cavity 223. Moreover, the toggle lever 3446 is inclined. The first end of the toggle lever 3446 is placed below the second end of the push rod 3445. The second end of the toggle lever 3446 tilts upward. And the position of the second end of the toggle lever 3446 is above the second end of the push rod 3445. The second end of the toggle lever 3446 is connected to the first end of the pull rope 3447. The second end of the pull rope 3447 passes through the moving cylinder 22 and is located outside the moving cylinder 22. When the staff member pulls down the second end of the pull rope 3447, the pull rope 3447 drives the second end of the toggle lever 3446 to move downward, and then drives the first end of the toggle lever 3446 to move upward. Then the first end of the toggle lever 3446 pushes the second end of the push rod 3445, so that the first end of the push rod 3445 moves upward in the sliding groove 222. Then the end of the first end of the push rod 3445 pushes against the control ring 3441, causing the control ring 3441 to move into the annular groove 311.

[0069] During specific implementation, a rectangular groove 224 is formed in the outer wall of the moving cylinder 22. The second ends of the pull ropes 3447 in each pushing unit are all located in the rectangular groove 224. Specifically, a wire passing groove is arranged at the bottom of the accommodation cavity 223 of the moving cylinder 22 in each pushing unit. Each wire passing groove communicates with the top of the rectangular groove 224. The pull ropes 3447 in each pushing unit are all placed in the corresponding wire passing grooves. And the pull ropes 3447 converge in the rectangular groove 224, which is convenient for the staff member to pull the pull ropes 3447.

[0070] During specific implementation, each sliding groove 222 can be a dovetail groove or a T-shaped groove. In this way, when the push rod 3445 slides in the sliding groove 222, the push rod 3445 can be limited, preventing the push rod 3445 from falling off when sliding.

[0071] See Figures 1 to 3 、 Figure 9 and Figure 10 In the above-mentioned embodiments, the base 1 includes: a base 11, a pressing plate 12, a plurality of moving wheels 13, a plurality of elastic telescopic rods, a plurality of fixing rods 14 and a third driving mechanism 15. Among them, the top of the base 11 is connected to the bottom of the support cylinder 2. The moving wheels 13 are arranged at intervals at the bottom of the base 11. The base 11 is driven to move by the moving wheels 13, realizing the mobility of the base 1. And a receiving cavity 111 that is recessed from the top to the bottom is further formed at the bottom of the base 11. Specifically, the moving wheels 13 are arranged at the corner positions at the bottom of the base 11, and the receiving cavity 111 is located at the middle part of the bottom of the base 11.

[0072] The pressing plate 12 is connected to the bottom wall of the storage cavity 111 through each elastic telescopic rod. Specifically, the bottom wall of the storage cavity 111 faces the ground. A plurality of elastic telescopic rods are arranged at intervals on the bottom wall of the storage cavity 111. The pressing plate 12 is connected to each elastic telescopic rod, so that the pressing plate 12 is parallel to the bottom wall of the storage cavity 111, and the pressing plate 12 seals the opening of the storage cavity 111. By providing the elastic telescopic rods, elastic force can be provided to the pressing plate 12 and guiding can be carried out during the movement of the pressing plate 12.

[0073] Each fixing rod 14 is arranged at intervals on the side of the pressing plate 12 facing the ground. Then, each fixing rod 14 is placed outside the storage cavity 111, and each fixing rod 14 is in contact with the ground.

[0074] The third driving mechanism 15 is arranged on the base 11, and the third driving mechanism 15 is connected to the pressing plate 12. The third driving mechanism 15 is used to drive the pressing plate 12 to move towards the ground so that each fixing rod 14 is in contact with the ground. Specifically, each fixing rod 14 can be a rubber rod or a metal rod with a tip. The rubber rod is used to fix the base 1 through friction in the case of cement or relatively hard geology, and the metal rod with a tip is used to fix the base 1 by inserting into the ground in muddy or sandy land.

[0075] The third driving mechanism 15 includes: a pedal 151, a transmission belt 152, two second rotating rods 153 and at least two cams 154. Among them, since the pressing plate 12 is connected to the bottom wall of the storage cavity 111 through a plurality of elastic telescopic rods, there is a certain space between the pressing plate 12 and the bottom wall of the storage cavity 111. The transmission belt 152, the two second rotating rods 153 and each cam 154 are all arranged in the space between the pressing plate 12 and the bottom wall of the storage cavity 111.

[0076] The two second rotating rods 153 are arranged in parallel, and the two second rotating rods 153 are rotatably arranged in the storage cavity 111. The transmission belt 152 is arranged between the two second rotating rods 153. At least one cam 154 is arranged on each second rotating rod 153, and the arrangement modes of the cams 154 on the two second rotating rods 153 are the same.

[0077] The pedal 151 is slidably arranged on one side of the base 11, and the pedal 151 is connected to one of the second rotating rods 153. The pedal 151 is used to drive the second rotating rod 153 to rotate under the action of an external force, and drive the other second rotating rod 153 to rotate through the transmission belt 152. Then, the rotation of the two second rotating rods 153 drives the cams 154 thereon to rotate, and each cam 154 pushes the pressing plate 12 to move towards the ground. Preferably, a fixing member is arranged between the pedal 151 and the base 11, and the fixing member can be a bolt to fix the position of the pedal 151.

[0078] Preferably, a rack is provided on one side of the pedal 151, and a gear is provided on one of the second rotating rods 153. The gear meshes with the rack. When the pedal 151 is stepped on, the movement of the pedal 151 drives the rotation of the second rotating rod 153.

[0079] During specific implementation, the number of cams 154 on each second rotating rod 153 can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. In this embodiment, two cams 154 are provided on each second rotating rod 153.

[0080] Combined with the attached Figure 1 to the attached Figure 10 The use process of the construction auxiliary device will be introduced:

[0081] (1) Push the base 1, and drive the construction auxiliary device to move to the required position through the moving wheels 13. Step on the pedal 151, and the movement of the pedal 151 drives the rotation of the second rotating rod 153 connected thereto. The second rotating rod 153 drives the rotation of another second rotating rod 153 through the transmission belt 152. The cams 154 on the two second rotating rods 153 also rotate accordingly and then squeeze the pressing plate 12, causing the pressing plate 12 to move towards the ground, and then driving the fixing rods 14 to move towards the ground, so that the fixing rods 14 contact and squeeze the ground, thereby fixing the base 1, that is, fixing the position of the construction auxiliary device.

[0082] (2) Adjust the height of the lamp 4: Rotate the first self-locking rotating handle 233. The first self-locking rotating handle 233 drives the rotation of the connecting rod 231. The rotation of the connecting rod 231 drives the rotation of the driving bodies 232. The driving bodies 232 frictionally engage with or mesh with the moving cylinder 22, thereby driving the moving cylinder 22 to extend out of the fixed cylinder 21, adjusting the height of the support cylinder 2, and realizing the height adjustment of the lamp 4.

[0083] (3) Adjust the irradiation position of the lamp 4: Rotate the second self-locking rotating handle 3425. The rotation of the second self-locking rotating handle 3425 drives the rotation of the first rotating rod 3421. The rotation of the first rotating rod 3421 drives the rotation of the driving rod 3423 through the bevel gear, and then drives the rotation of the telescopic cylinder 3424. The telescopic cylinder 3424 drives the rotation of the transmission rod 341. The rotation of the transmission rod 341 drives the rotation of the rotating plate 31 through the pressing blocks 3442, realizing the adjustment of the irradiation position of the lamp 4.

[0084] (4) Adjust the irradiation angle of the lamp 4: Pull down each pull cord 3447. Each pull cord 3447 pulls the second end of the corresponding rocker 3446 downward, causing the first end of the rocker 3446 to tilt upward. Then, the end of the first end of the rocker 3446 pushes the second end of the push rod 3445, causing the first end of the push rod 3445 to slide within the sliding groove 222. The end of the first end of the push rod 3445 contacts and pushes against the control ring 3441, causing the control ring 3441 to move towards the bottom wall of the annular groove 311. The movement of the control ring 3441 drives the movement of the annular extrusion body 3444. The annular extrusion body 3444 cooperates with the notches 34421 of the respective extrusion blocks 3442 through the inclined surface. Moreover, the annular extrusion body 3444 extrudes the respective extrusion blocks 3442, causing the respective extrusion blocks 3442 to move towards the outer annular wall of the annular groove 311. Then, the respective extrusion blocks 3442 are separated from the transmission rod 341, and the respective extrusion blocks 3442 no longer restrict the transmission rod 341. After adjusting the irradiation position of the lamp 4 in step (3), rotate the second self-locking rotary handle 3425 again. The rotation of the second self-locking rotary handle 3425 drives the rotation of the transmission rod 341. Since the respective push rods 3445 squeeze the control ring 3441, the position of the rotating plate 31 is restricted, thereby preventing the rotating plate 31 from rotating. Then, the rotation of the transmission rod 341 drives the rotation of the threaded rod 3433, drives the movement of the threaded cylinder, and further drives the slider 3431 to slide within the guide groove 331, causing the inclined plate 33 to rotate, thereby adjusting the inclination angle of the inclined plate 33 and realizing the adjustment of the irradiation angle of the lamp 4.

[0085] In summary, in this embodiment, the bottom of the telescopic support cylinder 2 is arranged on the base 1, and the lamp 4 is arranged at the top of the support cylinder 2. The height of the lamp 4 can be adjusted by the self-expansion and contraction of the support cylinder 2. Moreover, the position of the support device 3 at the top of the support cylinder 2 can be adjusted circumferentially, enabling the position of the lamp 4 to be adjusted circumferentially, realizing the adjustment of the irradiation position of the lamp 4. Additionally, the support device 3 itself can be tilted, realizing the adjustment of the irradiation angle of the lamp 4. In this way, the height, irradiation position, and irradiation angle of the lamp 4 can be adjusted according to actual needs, realizing the adjustment of the position of the lamp 4, enabling the lighting of the lamp 4 to better meet the construction requirements, and being able to better assist in construction. Moreover, the base 1 can be moved, driving the movement of the lamp 4, and can be moved to the required position according to needs to meet the lighting requirements of construction, with simple and convenient operation.
