Detailed Description

The utility model is described in further detail below with reference to fig. 1-3.

The embodiment of the utility model discloses a bracket removing clamp. Referring to fig. 1, it comprises a binding clip 1, a hinge 2 and two handles 3. The clamp head 1 is fixedly connected to one side of the hinge part 2, and the two clamp handles 3 are fixedly connected to one side of the hinge part 2 away from the clamp head 1.

Referring to fig. 2 and 3, an anti-slip sleeve 4 made of silica gel material is sleeved on the outer side of each clamp handle 3, and the anti-slip sleeve 4 can improve the anti-slip performance of the clamp handles 3. The outer side wall of the anti-slip sleeve 4 is provided with a plurality of anti-slip strips 43 along the length direction of the anti-slip sleeve 4 at intervals, and the anti-slip strips 43 can improve the roughness of the outer surface of the anti-slip sleeve 4 and further improve the anti-slip property of the outer surface of the anti-slip sleeve 4. The outer side wall of one end of the anti-skid sleeve 4 far away from the clamp head 1 is integrally formed with a limit protrusion 44; when the user's hand slides to one end of the anti-slip sleeve 4, the stopper protrusion 44 collides with the user's finger, thereby preventing the finger from being accidentally separated from the anti-slip sleeve 4.

Referring to fig. 2 and 3, the clamp handle 3 is provided with a fixing hole 31, a fixing column 5 with an annular section is penetrated in the fixing hole 31, and the anti-slip sleeve 4 is penetrated with a connecting hole 41 for the fixing column 5 to penetrate. One end of the fixed column 5 is fixed with a circular fixed plate 51 which is used for propping the anti-slip sleeve 4, the other end of the fixed column is detachably connected with a circular limiting plate 52 which is used for propping the anti-slip sleeve 4, the limiting plate 52 and the fixed plate 51 are both arranged on the same axis as the fixed column 5, and the diameters of the limiting plate 52 and the fixed plate 51 are both larger than the diameter of the fixed column 5. The limiting plate 52 is fixedly connected with a limiting screw 53, and the fixing column 5 is provided with a limiting hole 54 in threaded connection with the limiting screw 53. The fixing column 5 passes through the connecting hole 41 on the anti-skid sleeve 4 and then is inserted into the fixing hole 31, and then the limit screw 53 on the limit plate 52 is screwed into the limit hole 54, so that the pressure of the fixing plate 51 and the limit plate 52 is equalized to tightly press the anti-skid sleeve 4, and the anti-skid sleeve 4 is fixed on the clamp handle 3.

Referring to fig. 2 and 3, a positioning hole 42 is formed in one end, far away from the clamp head 1, of the anti-slip sleeve 4, a positioning bolt 6 for pressing the end part of the anti-slip sleeve 4 is arranged in the positioning hole 42 in a penetrating mode, and the positioning bolt 6 is in threaded connection with the end part of the clamp handle 3. After the anti-skid cover 4 is sleeved on the clamp handle 3, the screw rod of the positioning bolt 6 is inserted into the positioning hole 42 and screwed into the limiting hole 54 on the clamp handle 3, so that the nut of the positioning bolt 6 compresses the anti-skid cover 4, and the connection firmness between the anti-skid cover 4 and the clamp handle 3 is improved.

Referring to fig. 2 and 3, a positioning bar 312 is fixedly connected to the inner side wall of the fixing hole 31, and a positioning groove 55 into which the positioning bar 312 is clamped is provided in the outer side wall of the fixing column 5 along the length direction of the fixing column. When the fixed column 5 is inserted into the fixed hole 31, the positioning strip 312 is clamped into the positioning groove 55, so that the fixed column 5 is limited to rotate in the fixed hole 31, and therefore, when the limit screw 53 is screwed into the limit hole 54, the fixed column 5 cannot rotate, and the limit screw 53 is more convenient to install.

Referring to fig. 2 and 3, a fastening pad 311 made of a silica gel material is fixedly connected to an inner sidewall of the fixing hole 31, and one side of the fastening pad 311 abuts against an outer sidewall of the fastening post 5. The fastening pad 311 can fill up the gap between the fixing post 5 and the fixing hole 31, thereby reducing the shaking of the fixing post 5 in the fixing hole 31.

The embodiment of the utility model provides a bracket removing clamp, which comprises the following implementation principles: when the anti-slip sleeve 4 on the clamp handle 3 is damaged, the limit screw 53 is screwed out of the limit hole 54, so that the limit plate 52 is separated from the fixed column 5, the fixed column 5 is pulled out of the fixed hole 31, and then the positioning bolt 6 is screwed out of the positioning hole 42, so that the anti-slip sleeve 4 can be detached from the clamp handle 3, and a new anti-slip sleeve 4 can be conveniently replaced, so that the clamp handle 3 always has good anti-slip performance.

The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
