[0035] The cylindrical base 1 is provided with a positioning groove 3, which cooperates with the workpiece to fix the position of the workpiece relative to the cylindrical base 1.

[0036] In this embodiment, the positioning groove 3 is an arc-shaped through groove that is symmetrically distributed.

[0037] The mounting sleeve is mounted on the cylindrical base 1, and a sliding mounting component 5 is provided on the mounting sleeve. The sliding mounting component 5 is connected to the connecting baffle 208, which allows the connecting baffle 208 to slide relative to the mounting sleeve.

[0038] In a further preferred embodiment, the mounting sleeve includes an outer sleeve 6 and an inner sleeve 201;

[0039] The inner sleeve 201 is detachably fitted into the outer sleeve 6. The inner sleeve 201 has a first groove 4, which is used to limit the pin and position the pin hole.

[0040] To prevent relative movement between the inner sleeve 201 and the outer sleeve 6, a further preferred embodiment includes a fixing component. It is understood that the fixing component can employ various fixing methods such as bolts and clips.

[0041] In this embodiment, see Figure 5 The fixing assembly includes a connecting horizontal plate 501, a spring 502 and a vertical plate 503, and the fixing assembly has the advantage of easy disassembly.

[0042] A cavity is provided on the contact surface between the outer sleeve 6 and the inner sleeve 201. One end of the spring 502 is fixed to the outer sleeve 6, and the other end of the spring 502 is fixed to the vertical plate.

[0043] The inner sleeve 201 is provided with a fixing groove that is the same shape as the connecting horizontal plate 501. The spring 502 pushes the vertical plate, so that the vertical plate pushes the horizontal plate to be fixed in the fixing groove on the inner sleeve 201.

[0044] It is understood that the sliding mounting assembly 5 can be a spring 502 push rod or other external push rod. In this embodiment, see [reference needed]. Figure 4 The sliding mounting assembly 5 includes a connecting rack 207, a gear 205, and a gear connecting rod;

[0045] The inner sleeve 201 is provided with a connecting rod mounting hole, and the gear connecting rod is installed in the connecting rod mounting hole;

[0046] The lower part of the gear connecting rod is connected to the gear 205, and the rotation of the gear connecting rod drives the gear 205 to rotate.

[0047] The gear 205 meshes with the connecting rack 207, and the connecting rack 207 is connected to the connecting baffle 208.

[0048] To further improve the accuracy and ease of use of the sliding mounting component 5,

[0049] The sliding mounting assembly 5 has two sets, including two sets of connecting rack 207, gear 205, and gear connecting rod. The gear connecting rods are respectively the first gear connecting rod 203 and the second gear connecting rod 204.

[0051] The sliding mounting assembly 5 includes a handle 202;

[0052] The handle 202 is vertically mounted on the upper part of the gear connecting rod, and the function of the handle 202 is to facilitate rotation operation.

[0053] In use, the inner sleeve is first fitted onto the workpiece, and the symmetrical positioning grooves on the cylindrical base are used to position the parts, so as to quickly position the parts and restrict the parts, thereby reducing the difficulty of installation.

[0054] The connecting horizontal plate is placed in the cavity between the outer sleeve and the inner sleeve. One end of the spring is fixedly connected to the outer sleeve and the other end is fixedly connected to the vertical plate. The vertical plate is fixed by the elastic force of the spring. Then, the vertical plate is used to limit the connecting horizontal plate, so as to fix the inner ring assembly to the outer ring assembly.

[0055] When the sliding connecting baffle is in operation, rotating the handle drives the first gear connecting rod and the second gear connecting rod to rotate, which in turn drives the gears to rotate. The gears mesh with each other, causing the rack to slide, which in turn causes the connecting baffle to slide out of the inner sleeve and fit tightly against the workpiece, thus achieving the purpose of fixing the workpiece. The fixing method in this embodiment is simple in design, which is conducive to disassembly and maintenance. The fixing method protects the components and eliminates safety hazards during disassembly and maintenance.
