Description

TECHNICAL FIELD

[0001] The present application relates to the field of experimental apparatus, in particular to a clamping mechanism and a TIP head rack quick dismounting clamping device. BACKGROUND

[0002] The TIP head, also known as a pipette tip, can be used on an automatic or semi-automatic pipetting device for taking and dispensing solutions, and is one of the essential experimental consumables in biological and chemical experiments.

[0003] The TIP head rack is a device for fixing and supporting the TIP head. When in use, the TIP head rack is usually mounted on a rack seat in a TIP head box body. In order to fix the TIP head rack, a spring sheet is usually arranged in the TIP head box body, and the TIP head rack is clamped and fixed on the rack seat by the spring sheet. However, due to the influence of factors such as long-term stress or vibration, the elasticity of the spring sheet may gradually weaken, resulting in a decrease in fixing stability. In addition, if the TIP head rack and the spring sheet do not match well, the TIP head rack may also be loose or fall off. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the problem of insufficient stability of the spring sheet in fixing the TIP head rack, the present application provides a clamping mechanism and a TIP head rack quick dismounting clamping device.

[0005] The clamping mechanism provided by the present application adopts the following technical scheme:

[0006] The clamping mechanism comprises:

[0007] The fixing member is arranged at least two, respectively abutting to both sides of the clamped object;

[0008] The rotating member is rotatably arranged on the fixing member, and the rotating member is configured to rotate between a first position and a second position. One side of the rotating member is provided with a protruding portion. When the rotating member is in the first position, the lower end surface of the protruding portion abuts to the upper end surface of the clamped object, so as to limit the upward movement of the clamped object. When the rotating member is in the second position, the protruding portion is away from the clamped object, so as to release the locking of the clamped object.

[0009] The locking assembly is used for locking the rotating member in the first position.

[0010] Further, the locking assembly comprises a spring ball head plunger mounted on the fixing member, and the rotating member is provided with a locking hole for accommodating the ball head of the spring ball head plunger. When the rotating member is in the first position, the ball head of the spring ball head plunger is inserted into the locking hole.

[0011] Further, the locking assembly further comprises a rotation limiting structure for limiting the rotation angle of the rotating member.

[0012] Further, the rotation limiting structure comprises a limiting column fixed to the fixed member, and an angle of the rotating member is provided with a wedge surface.

[0013] When the rotating member is located at the second position, the limiting column abuts against one end of the wedge surface, thereby playing a limiting role.

[0014] Further, the rotation limiting structure further comprises a limiting protrusion fixed to one side of the wedge surface, and when the rotating member is located at the second position, the limiting column abuts against the limiting protrusion.

[0015] The limiting protrusion limits the rotating track of the rotating member, thereby limiting the rotating angle of the rotating member within a certain range, so that the rotating member can only rotate between the first position and the second position. In this way, the rotating member is prevented from being excessively rotated, and the convenience of operation is improved.

[0016] Further, a distance is provided between the rotating member and the fixed member, and the distance is not greater than the stroke distance of the ball head of the spring ball head plunger.

[0017] Further, the fixed member is provided with a fixed screw, the rotating member is provided with a threaded hole which is threadedly matched with the fixed screw, and the rotating member is provided with a distance limiting structure for controlling the distance between the rotating member and the fixed member.

[0018] When the distance between the rotating member and the fixed member is greater than the stroke distance of the ball head of the spring ball head plunger, even if the ball head is fully extended, it cannot be inserted into the locking hole, resulting in failure of the spring ball head plunger and failure to achieve locking of the rotating member. Therefore, the distance limiting structure is required to control the distance between the rotating member and the fixed member, so that the distance is not greater than the stroke distance of the ball head of the spring ball head plunger, thereby avoiding the distance between the rotating member and the fixed member being too large and causing failure of the spring ball head plunger.

[0019] Further, the distance limiting structure comprises a clamping screw threadedly connected to the rotating member, the end of the clamping screw and the end of the fixed screw are located in the threaded hole, and the end of the clamping screw abuts against the end of the fixed screw.

[0020] Before the rotating member is installed, the clamping screw is screwed into the threaded hole to a certain depth; when the rotating member is installed, the fixed screw is inserted through the through hole of the fixed member and then screwed into the threaded hole of the rotating member, until the end of the fixed screw abuts against the end of the clamping screw, thereby fixing the distance between the rotating member and the fixed member.

[0021] By adjusting the depth of the fixing screw screwed into the threaded hole, the depth of the fixing screw screwed into the threaded hole can be controlled, thereby adjusting the distance between the rotating member and the fixed member, so that the ball head of the spring ball head plunger works in a suitable stroke range, which can not only avoid the distance between the rotating member and the fixed member being too large to cause the spring ball head plunger to fail, but also avoid the distance between the rotating member and the fixed member being too small to cause the spring in the spring ball head plunger to be compressed difficultly.

[0022] Further, the threaded hole is a blind hole, and the end of the fixing screw abuts against the bottom wall of the threaded hole.

[0023] When the rotating member is installed, the fixing screw is passed through the through hole on the fixed member and then screwed into the threaded hole on the rotating member until the end of the fixing screw abuts against the bottom wall of the threaded hole, so as to fix the distance between the rotating member and the fixed member.

[0024] Further, the rotating member is fixedly provided with a pushing block for driving the rotating member to rotate.

[0025] The operator can conveniently drive the rotating member to rotate by pushing the pushing block, thereby improving the convenience of locking and unlocking the TIP head frame.

[0026] The TIP head frame quick dismounting and clamping device provided by the application adopts the following technical scheme:

[0027] A TIP head frame quick dismounting and clamping device, comprising:

[0028] a frame seat for bearing the TIP head frame;

[0029] a positioning mechanism for positioning the TIP head frame on the frame seat;

[0030] a clamping mechanism for fixing the TIP head frame on the frame seat, the clamping mechanism comprising:

[0031] a fixed member fixedly arranged on the frame seat, the fixed member being provided with at least two and abutting against two sides of the TIP head frame respectively;

[0032] a rotating member rotatably arranged on the fixed member, the rotating member being configured to rotate between a first position and a second position; one side of the rotating member is provided with a protruding portion, when the rotating member is in the first position, the lower end surface of the protruding portion abuts against the upper end surface of the TIP head frame, for limiting the upward movement of the TIP head frame; when the rotating member is in the second position, the protruding portion is away from the TIP head frame, so that the TIP head frame is unlocked;

[0033] a locking assembly for locking the rotating member in the first position.

[0034] Further, two side wings are arranged on the two sides of the TIP head frame, and the lower end surface of the protruding part abuts against the upper end surface of the side wing when the rotating part is in the first position.

[0035] Further, the side surface of the fixing part abuts against the side wing.

[0036] When it is needed to fix the TIP head frame on the frame seat, the rotating part is rotated towards the TIP head frame, so that the ball head in the spring ball head plunger is stretched out and inserted into the locking hole under the deformation force of the spring, thereby locking the rotating part on the fixing part; at this time, the lower end surface of the protruding part on the rotating part abuts against the upper end surface of the side wing of the TIP head frame, thereby limiting the upward movement of the TIP head frame and avoiding the TIP head frame from falling off the frame seat.

[0037] Compared with the common way of fixing the TIP head frame by using elastic sheets, the fixing way provided by the application is not easily affected by factors such as vibration, and there is no problem of reduced elasticity of the elastic sheets due to long-term use, so that the fixing way of the application can make the stability of the TIP head frame higher.

[0038] When it is needed to release the locking of the TIP head frame on the frame seat, the rotating part is rotated away from the TIP head frame, in the process, the lower end surface of the rotating part extrudes the ball head in the spring ball head plunger, so that the spring in the spring ball head plunger is compressed, and as the rotating part rotates, the ball head slides out of the locking hole, thereby releasing the position locking of the rotating part on the fixing part; at this time, the lower end surface of the protruding part on the rotating part no longer abuts against the upper end surface of the side wing of the TIP head frame, thereby realizing the quick unlocking of the TIP head frame and facilitating the removal of the TIP head frame from the frame seat.

[0039] Further, the positioning mechanism comprises a protruding edge arranged on the two sides of the frame seat, and the protruding edge is clamped and fitted with the side wing.

[0040] When the TIP head frame is installed on the frame seat, the side wings on the two sides of the TIP head frame are clamped on the protruding edges on the two sides of the frame seat, thereby positioning the TIP head frame.

[0041] Further, the positioning mechanism comprises two corner limiting blocks arranged on one end of the frame seat, and the two corner limiting blocks abut against the two corners of the TIP head frame, respectively.

[0042] When the TIP head frame is installed on the frame seat, the two corner limiting blocks abut against the two corners of the TIP head frame, respectively, thereby positioning the TIP head frame.

[0043] Further, the positioning mechanism comprises a positioning column and a positioning groove arranged on the frame seat and the TIP head frame, respectively.

[0044] When the TIP head frame is installed, the positioning column is clamped in the positioning groove, thereby positioning the TIP head frame in the installation direction.

[0045] Further, the positioning mechanism comprises side limiting blocks arranged on both sides of the frame seat, and the two side limiting blocks abut against two sides of the TIP head frame, respectively.

[0046] When the TIP head frame is installed on the frame seat, the two side limiting blocks abut against two sides of the TIP head frame, respectively, thereby positioning the TIP head frame in position.

[0047] The above multiple positioning mechanisms simultaneously position the TIP head frame, which is conducive to improving the accuracy of positioning and the stability of fixation, facilitating the rapid installation of the TIP head frame, and effectively preventing the TIP head frame from moving in the horizontal plane during use.

[0048] Further, the two side limiting blocks are diagonally arranged on the frame seat.

[0049] Further, the two rotating members are diagonally arranged on the frame seat, and the two side limiting blocks and the two rotating members are located at four corners of the frame seat, respectively.

[0050] In this way, the accuracy of positioning and the stability of fixation of the TIP head frame are improved.

[0051] In summary, the present application has the following beneficial technical effects:

DETAILED DESCRIPTION

[0063] The following will be described in detail below with reference to the accompanying drawings Figures 1-9 The present application will be further described in detail.

[0064] Embodiment 1

[0065] The present application discloses a clamping mechanism. Referring to Figure 1 and Figure 2 , the clamping mechanism comprises:

[0066] The fixed member 42 is provided with at least two, respectively abutting the two sides of the clamped object;

[0067] The rotating member 41 is rotatably arranged on the fixed member 42, and the rotating member 41 is configured to rotate between the first position and the second position; one side of the rotating member 41 is provided with a convex part 411, when the rotating member 41 is in the first position, as shown in Figure 1 , the lower end surface of the convex part 411 abuts the upper end surface of the clamped object, for limiting the upward movement of the clamped object; when the rotating member 41 is in the second position, as shown in Figure 2 , the convex part 411 is away from the clamped object, so that the clamped object is unlocked;

[0068] Further, a locking assembly is provided to lock the rotating member 41 in the first position.

[0069] Specifically, referring to Figure 3 and Figure 4 , the fixing member 42 is provided with a through hole 422 for the fixing screw 43 to pass through, and the rotating member 41 is provided with a threaded hole 414 for the fixing screw 43 to threadedly connect with. During installation, the fixing screw 43 is passed through the through hole 422 on the fixing member 42 and then threadedly connected with the rotating member 41, so that the rotating member 41 is rotationally connected with the fixing member 42, and the rotation axis is vertically arranged. The fixing member 42, the rotating member 41, the fixing screw 43 and the like can be made of plastic or metal.

[0070] Referring to Figure 3 and Figure 4 , the protruding portion 411 is arranged on the side of the rotating member 41 close to the clamped object, and the protruding portion 411 and the rotating member 41 can be integrally formed. When the rotating member 41 is rotated to the first position, the side surface of the rotating member 41 is flush with the side surface of the fixing member 42, and the lower end surface of the protruding portion 411 abuts against the upper end surface of the clamped object, so as to limit the upward movement of the clamped object.

[0071] In order to ensure the stability of the clamped object and avoid the situation that the clamped object falls off due to the loosening of the rotating member 41 caused by external disturbances such as vibration, the locking assembly is used to lock the rotating member 41 in the first position, specifically as follows:

[0072] Referring to Figure 3 and Figure 4 , the locking assembly comprises a spring ball plunger 45 installed on the fixing member 42, and the spring ball plunger 45 can be fixed in the mounting hole 423 on the upper end surface of the fixing member 42 by interference, thread or adhesion. The spring ball plunger 45 comprises a base and a ball head elastically connected to the base by a spring, and the ball head can extend or retract within a certain stroke range as the spring expands and contracts.

[0073] Further, referring to Figure 3 , Figure 4 and Figure 5 , the rotating member 41 is provided with a locking hole 46 corresponding to the spring ball plunger 45 at a position on the rotating member 41, for accommodating the ball head of the spring ball plunger 45. In the present embodiment, the locking hole 46 is a through hole arranged on the rotating member 41; in other feasible embodiments, the locking hole 46 can also be a blind hole arranged on the lower end surface of the rotating member 41.

[0074] In order to realize the locking and unlocking of the rotating member 41, the distance between the rotating member 41 and the fixed member 42 during installation needs to be considered. If the distance between the rotating member 41 and the fixed member 42 is greater than the stroke distance of the ball head in the spring ball head plunger 45, even if the ball head is fully extended, it cannot be inserted into the locking hole 46, resulting in the failure of the spring ball head plunger 45 and the inability to realize the locking of the rotating member 41. On the other hand, if the distance between the rotating member 41 and the fixed member 42 is too small, it may cause difficulty in compressing the spring in the spring ball head plunger 45. Further, if the distance between the rotating member 41 and the fixed member 42 is less than the stroke distance of the ball head in the spring ball head plunger 45, but the distance is large, when the ball head is inserted into the locking hole 46, the pressing force between the ball head and the locking hole 46 is not large enough, which may cause unstable locking of the rotating member 41. Therefore, a distance limiting structure needs to be used to control the distance between the rotating member 41 and the fixed member 42, so as to keep it within a suitable range.

[0075] Specifically, in the present embodiment, referring to Figure 3 、 Figure 4 and Figure 5 , a threaded hole 414 is formed through the rotating member 41, the distance limiting structure includes a set screw 44 threadedly connected to the rotating member 41, the end of the set screw 44 and the end of the fixed screw 43 are located in the threaded hole 414, and the end of the set screw 44 abuts against the end of the fixed screw 43.

[0076] Before installing the rotating member 41, the set screw 44 is screwed into the threaded hole 414 to a certain depth; when installing the rotating member 41, the fixed screw 43 is inserted through the through hole 422 on the fixed member 42 and then screwed into the threaded hole 414 on the rotating member 41 until the end of the fixed screw 43 abuts against the end of the set screw 44, thereby fixing the distance between the rotating member 41 and the fixed member 42.

[0077] By adjusting the depth of the set screw 44 screwed into the threaded hole 414, the depth of the fixed screw 43 screwed into the threaded hole 414 can be controlled, thereby adjusting the distance between the rotating member 41 and the fixed member 42, so that the ball head of the spring ball head plunger 45 works within a suitable stroke range, which can avoid the distance between the rotating member 41 and the fixed member 42 being too large to cause the failure of the spring ball head plunger 45, and can also avoid the distance between the rotating member 41 and the fixed member 42 being too small to cause difficulty in compressing the spring in the spring ball head plunger 45.

[0078] As another embodiment of the distance limiting structure, the threaded hole 414 is a blind hole formed in the lower end face of the rotating member 41, when installing the rotating member 41, the fixed screw 43 is inserted through the through hole 422 on the fixed member 42 and then screwed into the threaded hole 414 on the rotating member 41 until the end of the fixed screw 43 abuts against the bottom wall of the threaded hole 414, thereby fixing the distance between the rotating member 41 and the fixed member 42 and playing a distance limiting role.

[0079] Further, the locking assembly further comprises a rotation limiting structure for limiting the rotation angle of the rotating member 41. Specifically, referring to Figure 1 and Figure 2 , the rotation limiting structure comprises a limiting column 421 fixed to one corner of the upper end surface of the fixed member 42, and the limiting column 421 is vertically arranged and can be a square column, a circular column or other shapes; one corner of the rotating member 41 is provided with a wedge surface 412, and the wedge surface 412 functions to prevent the limiting column 421 from interfering with the rotation of the rotating member 41. In the embodiment, the wedge surface 412 is a flat surface, and in other feasible embodiments, the wedge surface 412 can also be an arc surface. The rotation limiting structure further comprises a limiting convex rib 413 fixedly arranged on one side of the wedge surface 412, and the limiting convex rib 413 is vertically arranged; when the rotating member 41 is located at the second position, as shown in Figure 2 , the limiting column 421 abuts against the limiting convex rib 413, and this position is the terminal point of the outward rotation of the rotating member 41.

[0080] The limiting convex rib 413 limits the rotation trajectory of the rotating member 41, thereby limiting the rotation angle of the rotating member 41 within a certain range, so that the rotating member 41 can only rotate between the first position and the second position, and within this range, the ball head in the spring ball head plunger 45 always abuts against the lower end surface of the rotating member 41. In this way, the rotating member 41 is prevented from being excessively rotated, and the convenience of operation is improved.

[0081] As described above, when the rotating member 41 is rotated to the first position, the ball head of the spring ball head plunger 45 is inserted into the locking hole 46 to lock the rotating member 41, that is, the locking assembly functions to limit the rotation of the rotating member 41, and the rotation of the rotating member 41 towards the inner side does not need to be limited by an additional rotation limiting structure, so only the limiting convex rib 413 needs to be arranged on one side of the wedge surface 412 for limiting the outward rotation of the rotating member 41.

[0082] In another feasible embodiment, the limiting convex rib 413 can not be arranged, and only the wedge surface 412 is used for limiting; when the rotating member 41 is located at the second position, the limiting column 421 abuts against one end of the wedge surface 412 to function as a limiting structure.

[0083] In order to improve the convenience of locking and unlocking, referring to Figure 3 and Figure 4 , the upper end surface of the rotating member 41 is fixedly provided with a pushing block 415, and the operator can conveniently drive the rotating member 41 to rotate by pushing the pushing block 415.

[0084] The implementation principle of the clamping mechanism in the embodiment of the present application is as follows: the clamped object is positioned between the two fixing members 42, and then the rotating member 41 is rotated towards the clamped object, so that the rotating member 41 reaches the first position, the ball head in the spring ball head plunger 45 extends and inserts into the locking hole 46 under the deformation force of the spring, thereby locking the rotating member 41 on the fixing member 42. At this time, the lower end surface of the protruding portion 411 on the rotating member 41 abuts against the upper end surface of the clamped object, thereby limiting the upward movement of the clamped object and achieving the fixation of the clamped object.

[0085] When it is necessary to release the locking of the clamped object, the rotating member 41 is rotated away from the clamped object, in the process, the lower end surface of the rotating member 41 extrudes the ball head in the spring ball head plunger 45, so that the spring in the spring ball head plunger 45 is compressed, and as the rotating member 41 rotates, the ball head slides out of the locking hole 46, thereby releasing the position locking of the rotating member 41 on the fixing member 42; at this time, the lower end surface of the protruding portion 411 on the rotating member 41 no longer abuts against the upper end surface of the clamped object, thereby achieving the quick unlocking of the clamped object.

[0086] Embodiment 2

[0087] Based on the above clamping mechanism, the embodiment of the present application further discloses a TIP head rack quick dismounting and clamping device. Referring to Figure 6 and Figure 7 , the TIP head rack quick dismounting and clamping device comprises:

[0088] a rack seat 1 for carrying a TIP head rack 2;

[0089] a positioning mechanism 3 for positioning the TIP head rack 2 on the rack seat 1;

[0090] a clamping mechanism 4 for fixing the TIP head rack on the rack seat, the clamping mechanism 4 adopts the structure described in Embodiment 1 and comprises:

[0091] a fixing member 42 fixedly arranged on the rack seat 1, the fixing member 42 is provided with at least two, which abut against the two sides of the TIP head rack 2 respectively;

[0092] a rotating member 41 rotatably arranged on the fixing member 42, the rotating member 41 is configured to rotate between a first position and a second position; one side of the rotating member 41 is provided with a protruding portion 411, when the rotating member 41 is in the first position, the lower end surface of the protruding portion 411 abuts against the upper end surface of the TIP head rack 2, for limiting the upward movement of the TIP head rack 2; when the rotating member 41 is in the second position, the protruding portion 411 is away from the TIP head rack 2, so that the TIP head rack 2 is released from the locking;

[0093] a locking assembly for locking the rotating member 41 in the first position; the structure and use mode of the locking assembly are the same as those of Embodiment 1.

[0094] The role of the bracket 1 in the present application is to carry the TIP head bracket 2, so the shape of the bracket 1 is not limited. Since the commonly used TIP head bracket 2 is rectangular, as shown in Figure 6 the bracket 1 in the present application is a rectangular frame, including a rectangular base 11, a square-shaped supporting seat 13, and four supporting columns 12 fixedly connected between the base 11 and the supporting seat 13. The TIP head bracket 2 is placed on the supporting seat 13, and the space between the base 11 and the supporting seat 13 is used to accommodate the TIP head. The material of the bracket 1 is not limited, and both plastic and metal can be used.

[0095] In use, first, the TIP head bracket 2 is positioned on the bracket 1 through the positioning mechanism 3, and then the TIP head bracket 2 is clamped and fixed on the bracket 1 through the clamping mechanism 4 cooperating with the locking assembly, which limits the upward movement of the TIP head bracket 2 and avoids the TIP head bracket 2 from falling off the bracket 1, thereby improving the stability of the TIP head bracket 2 during use. The structure and use of each mechanism are described below.

[0096] Referring to Figure 6 and Figure 8 , the positioning mechanism 3 includes a positioning column 132 fixedly arranged at a corner of the supporting seat 13, and one end of the TIP head bracket 2 is provided with a positioning groove 22 for accommodating the positioning column 132. The positioning column 132 can be a cylindrical column, a square column, etc., and correspondingly, the positioning groove 22 is a circular groove, a square groove, etc. adapted to the shape of the positioning column 132. In another embodiment, the positioning column 132 can be arranged at one end of the TIP head bracket 2, and correspondingly, the positioning groove 22 can be arranged on the supporting seat 13. When installing the TIP head bracket 2, the positioning column 132 is clamped in the positioning groove 22, thereby positioning the installation direction of the TIP head bracket 2.

[0097] Referring to Figure 8 , opposite sides of the TIP head bracket 2 are provided with side wings 21, and the side wings 21 are inverted L-shaped; opposite sides of the supporting seat 13 are provided with protrusions 131, and the distance between the two protrusions 131 is adapted to the distance between the two side wings 21. When the TIP head bracket 2 is installed on the bracket 1, the side wings 21 on both sides of the TIP head bracket 2 are clamped in the protrusions 131 on both sides of the bracket 1, thereby positioning the position of the TIP head bracket 2.

[0098] Referring to Figure 6 , Figure 8 and Figure 9 , the positioning mechanism 3 further includes two corner limiting blocks 133 fixedly arranged at one end of the supporting seat 13, and the corner limiting blocks 133 can be installed on the supporting seat 13 by screws. When the TIP head bracket 2 is installed on the bracket 1, the two corner limiting blocks 133 abut against the two corners of the TIP head bracket 2, thereby further positioning the position of the TIP head bracket 2.

[0099] Further, referring toFigure 8 and Figure 9 The positioning mechanism 3 further comprises side limiting blocks 31 fixed on both sides of the supporting seat 13. The side limiting blocks 31 are square blocks, which can be installed on the supporting seat 13 by two screws or by two positioning pins and a screw. When the TIP head frame 2 is installed on the frame seat 1, the two side limiting blocks 31 abut against the side wings 21 on both sides of the TIP head frame 2, thereby positioning the TIP head frame 2.

[0100] As a preferred embodiment, in the embodiment, the two side limiting blocks 31 are diagonally arranged on the supporting seat 13, so as to improve the positioning accuracy of the TIP head frame 2.

[0101] The application adopts multiple positioning mechanisms 3 to simultaneously position the TIP head frame 2, including the positioning column 132 cooperating with the positioning groove 22, the side wing 21 cooperating with the convex edge 131, and the angle limiting block 133 and the side limiting block 31 limiting the TIP head frame 2 in different directions, which is beneficial to improve the positioning accuracy and fixing stability, facilitate the rapid installation of the TIP head frame 2, and effectively avoid the movement of the TIP head frame 2 in the horizontal plane during use.

[0102] Referring to Figure 7 and Figure 9 The fixing member 42 is fixed on the supporting seat 13 and can be installed and fixed by two screws or by two positioning pins and a screw. In the embodiment, the fixing member 42 is provided with two, and the two side limiting blocks 31 and the two fixing members 42 are respectively located at the four corners of the supporting seat 13. The fixing member 42 is a square block, and when the TIP head frame 2 is installed on the frame seat 1, the two fixing members 42 abut against the side wings 21 on both sides of the TIP head frame 2, which can also position the TIP head frame 2.

[0103] In another feasible embodiment, the supporting seat 13 can not be provided with the side limiting block 31, and correspondingly, the fixing member 42 is provided with four, and the four fixing members 42 are respectively located at the four corners of the supporting seat 13.

[0104] In another feasible embodiment, the supporting seat 13 is provided with four side limiting blocks 31 and is respectively located at the four corners of the supporting seat 13, and the four side limiting blocks 31 abut against the side wings 21 on both sides of the TIP head frame 2 to limit the TIP head frame 2. The fixing member 42 is still provided with two, and at this time, the fixing member 42 can not abut against the side wings 21 on both sides of the TIP head frame 2, that is, the fixing member 42 does not limit the TIP head frame 2 in the lateral direction.

[0105] The implementation principle of the TIP head frame quick dismounting and clamping device provided in the embodiment of the application is as follows: when the TIP head frame 2 is installed, first, the TIP head frame 2 is positioned on the frame seat 1 through the positioning mechanism 3, then the rotating piece 41 is rotated towards the TIP head frame 2, so that the rotating piece 41 reaches the first position, the ball head in the spring ball head plunger 45 is stretched out and inserted into the locking hole 46 under the deformation force of the spring, so as to lock the rotating piece 41 on the fixing piece 42; at this time, the lower end surface of the protruding part 411 on the rotating piece 41 abuts against the upper end surface of the side wing 21 of the TIP head frame 2, so as to limit the upward movement of the TIP head frame 2 and avoid the TIP head frame 2 from falling off the frame seat 1.

[0106] It can be understood that when the TIP head frame 2 is placed on the frame seat 1, the upper end surface of the side wing 21 is slightly higher than the upper end surface of the fixing piece 42, and the height difference therebetween is the distance between the rotating piece 41 and the fixing piece 42, so that when the rotating piece 41 is rotated to the first position, the lower end surface of the rotating piece 41 abuts against the upper end surface of the side wing 21, so as to limit the upward movement of the TIP head frame 2.

[0107] Compared with the common way of fixing the TIP head frame 2 by using elastic sheets, the fixing way provided in the application is not easily affected by external disturbances such as vibration, and there is no problem of reduced elasticity of the elastic sheets due to long-term use, so that the fixing way provided in the application can make the TIP head frame 2 more stable.

[0108] When it is necessary to release the locking of the TIP head frame 2 on the frame seat 1, the rotating piece 41 is rotated away from the TIP head frame 2, in this process, the lower end surface of the rotating piece 41 extrudes the ball head in the spring ball head plunger 45, so that the spring in the spring ball head plunger 45 is compressed, and as the rotating piece 41 is rotated, the ball head slides out of the locking hole 46, so as to release the position locking of the rotating piece 41 on the fixing piece 42; at this time, the lower end surface of the protruding part 411 on the rotating piece 41 no longer abuts against the upper end surface of the side wing 21 of the TIP head frame 2, so as to realize the quick unlocking of the TIP head frame 2 and facilitate the removal of the TIP head frame 2 from the frame seat 1.

[0109] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made on the structure, shape and principle of the application should be covered in the protection scope of the application.
