[0032] Below is the attached figure Figures 1 to 6 The technical solution of the utility model is further illustrated through specific implementation methods.

[0033] Example 1

[0034] like Figure 1-3 As shown, a telescopic drive mechanism includes a fixed frame 1, a first drive assembly 2 and a first guide member 3;

[0035] The first drive assembly 2 and the first guide member 3 are arranged inside the fixed frame 1. The driving end of the first drive assembly 2 is installed with a fixed block 4. One end of the fixed block 4 is provided with a mounting arm 5. The mounting arm 5 is detachably connected to a guide cylinder 7. The guide cylinder 7 is connected to a second drive assembly 8. The driving end of the second drive assembly 8 is detachably installed with a water-cooling slider 6. The second drive assembly 8 is used to drive the water-cooling slider 6 to move along the axis of the guide cylinder 7.

[0036] The first guide member 3 is fixedly disposed on an inner side of the fixing frame 1;

[0037] The first driving assembly 2 is used to drive the fixed block 4 to move. The other side of the fixed block 4 is slidably connected to the first guide member 3. The first guide member 3 is used to guide the fixed block 4.

[0038] The fixed block 4 is driven to move by the first driving component 2. During the movement of the fixed block 4, the fixed block 4 is guided by the first guide member 3, which can drive the water-cooling slider 6 to move stably and smoothly to adjust the lateral position of the water-cooling slider 6. Then, the water-cooling slider 6 is driven to move by the second driving component 2 to adjust the longitudinal height of the water-cooling slider 6, thereby facilitating the user to quickly adjust the position of the water-cooling slider 6.

[0039] like Figure 2 As shown, a guide rail 31 is provided on one side of the fixing block 4 , and the guide rail 31 is slidably connected to the first guide member 3 .

[0040] Specifically, by using the guide rail 31 in conjunction with the first guide member 3 , the fixed block 4 can move more stably and smoothly, thereby driving the water-cooling slider 6 to move stably and smoothly through the fixed block 4 .

[0041] like Figure 3 As shown, the first driving assembly 2 includes a support plate 21, which is fixedly mounted on the inner wall of the fixed frame 1. A screw 22 is rotatably provided on the support plate 21, and a screw nut 26 is threadedly sleeved on one end of the screw 22. The screw nut 26 is detachably mounted on the fixed block 4, and the other end of the screw 22 is coaxially connected to a driving member 25.

[0042] like Figure 1-3 As shown, the driving member 25 includes a manual driving rod, a first bevel gear 23 and a second bevel gear 24. The manual driving rod passes through the fixed frame 1 and extends to the interior of the fixed frame 1 and is coaxially connected to the first bevel gear 23. The lead screw 22 passes through the support plate 21 and extends to the outside and is coaxially connected to the second bevel gear 24. The first bevel gear 23 is meshed with the second bevel gear 24.

[0043] Specifically, the first bevel gear 23 is driven to rotate by a manual driving rod, the first bevel gear 23 drives the meshing second bevel gear 24 to rotate, and the second bevel gear 24 drives the coaxially connected lead screw 22 to rotate. During the rotation of the lead screw 22, through the cooperation of the guide rail 31 and the first guide member 3, the lead screw nut 26 drives the fixed block 4 to move stably and smoothly in the fixed frame 1, and the movement of the fixed block 4 drives the mounting arm 5 to move, thereby adjusting the position of the water-cooling slider 6 installed on the mounting arm 5.

[0044] Further, such as Figure 3As shown, the fixing block 4 and the first bevel gear 23 and the second bevel gear 24 are respectively arranged on both sides of the support plate 21.

[0045] Specifically, the fixing block 4 and the first bevel gear 23 and the second bevel gear 24 are respectively arranged on both sides of the support plate 21 , which can prevent the first bevel gear 23 and the second bevel gear 24 from interfering with the movement of the fixing block 4 .

[0046] like Figure 3 As shown, a mounting hole 41 is provided on one side of the fixing block 4, the lead screw 22 is arranged to pass through the mounting hole 41, and the lead screw nut 26 is detachably mounted on one end of the fixing block 4 by a bolt, and one end of the lead screw nut 26 has a first protrusion 261, which is inserted into the mounting hole 41.

[0047] Specifically, by inserting the first protrusion 261 into the mounting through hole 41, the first protrusion 261 can support the screw 22 and increase the contact area between the screw 22 and the screw nut 26, thereby making the rotation of the screw 22 more stable.

[0048] like Figure 3 As shown, one end of the mounting arm 5 has a second protrusion 51, and the second protrusion 51 is inserted into the mounting through hole 41. The top of the fixing block 4 is provided with a first threaded hole 42 connected to the mounting through hole 41, and the top of the second protrusion 51 is provided with a second threaded hole. The second protrusion 51 is inserted into the mounting through hole 41 by means of a bolt passing through the first threaded hole 42 and the second threaded hole. The second protrusion 51 and the first protrusion 261 are both tightly fitted with the mounting through hole 41.

[0049] Specifically, the second protrusion 51 is inserted into the mounting through hole 41 by means of a bolt passing through the first threaded hole 42 and the second threaded hole, which can facilitate the assembly and disassembly between the mounting arm 5 and the fixing block 4 .

[0050] Furthermore, the first protrusion 261 and the second protrusion 51 are tightly fitted with the mounting through hole 41, so that the screw nut 26 and the mounting arm 5 are stably mounted together with the fixing block 4, thereby making the screw 22 more stable when rotating.

[0051] like Figure 3 As shown, a side wall of the second protrusion 51 is provided with an avoidance hole 52 adapted to the lead screw 22 , and one end of the lead screw 22 is rotatably inserted into the avoidance hole 52 .

[0052] Specifically, the avoidance hole 52 and the support plate 21 can support both ends of the lead screw 22 respectively, so that the lead screw 22 is more stable when rotating.

[0053] like Figure 6 As shown, the second driving assembly 8 includes a screw 81 and a T-shaped rod 82. The screw 81 is threadedly installed in the interior of the guide cylinder 7. The top of the screw 81 is provided with a receiving groove 811. The T-shaped rod 82 is slidably installed in the receiving groove 811. The bottom end of the receiving groove 811 is provided with a guide hole. The bottom end of the T-shaped rod 82 slides through the guide hole and extends to the outside of the screw 81 to be threadedly connected to a connector 84. The bottom end of the connector 84 is detachably mounted with the water-cooling slider 6.

[0054] The outer portion of the connector 84 is sleeved with a second guide member 85 , the connector 84 is slidably connected to the second guide member 85 , the second guide member 85 is used to guide the connector 84 , and the second guide member 85 is detachably mounted inside the guide cylinder 7 ;

[0055] A spring 83 is connected between the connector 84 and the screw rod 81 , and the spring 83 is sleeved on the outside of the T-shaped rod 82 .

[0056] Specifically, when adjusting the water-cooled slider 6, the screw 81 is rotated so that the screw 81 moves along the axis of the guide cylinder 7. The movement of the screw 81 drives the connecting head 84 connected to the T-bar 82 to slide along the second guide member 85. The connecting head 84 drives the water-cooled slider 6 to move, thereby adjusting the longitudinal height of the water-cooled slider 6.

[0057] Furthermore, since the T-shaped rod 82 can slide along the guide hole in the receiving groove 811, during welding, under the action of the spring 83, the bottom end of the water-cooling slider 6 can be pressed against the surface of the welding workpiece.

[0058] Furthermore, the second guide member 85 is an internal gear sleeve, and the connecting head 84 is meshedly connected to the internal gear sleeve and can move along the axis of the internal gear sleeve, so that the moving direction of the connecting head 84 is guided by the second guide member 85, making the movement of the connecting head 84 more stable and smooth.

[0059] Example 2

[0060] like Figure 5 As shown, compared with embodiment 1, the difference is that the first guide member 3 is provided with an inner tooth hole, the outer periphery of the fixed block 4 is provided with an outer tooth sleeve 43 that matches the inner tooth hole, and the outer tooth sleeve 43 is limitedly set in the inner tooth hole. The first driving component 2 drives the fixed block 4 to move, driving the outer tooth sleeve 43 to slide along the inner tooth hole.

[0061] Example 3

[0062] like Figure 4As shown, compared with Example 1, the difference is that the driving member 25 is a driving motor, the driving motor is fixedly installed inside the fixed frame 1, the output shaft of the driving motor is coaxially connected to the screw 22, and the support plate 21 is located between the driving motor and the fixed block 4.

[0063] Specifically, by driving the lead screw 22 to rotate via the driving motor, the position of the water-cooling slider 6 can be adjusted when it is inconvenient to manually rotate the manual drive rod.

[0064] Example 4

[0065] like Figure 4 and 5 As shown, compared with embodiment 1, the difference is that the first guide member 3 is provided with an inner tooth hole, the outer periphery of the fixed block 4 is provided with an outer tooth sleeve 43 that matches the inner tooth hole, and the outer tooth sleeve 43 is limitedly set in the inner tooth hole. The first driving component 2 drives the fixed block 4 to move, driving the outer tooth sleeve 43 to slide along the inner tooth hole.

[0066] The driving member 25 is a driving motor, which is fixedly installed inside the fixing frame 1 . The output shaft of the driving motor is coaxially connected to the lead screw 22 . The support plate 21 is located between the driving motor and the fixing block 4 .
