The utility model provides the mounting cylinder, the mounting groove, the connecting strip, the pull rod, the plug rod and the reset spring so that the drill body can be replaced according to the size of the hole to be opened during use, so as to better work, and also conveniently replace the drill body when it is damaged, avoiding the need to replace different models of hammer drills when different sizes of holes need to be opened during work, resulting in the need to prepare multiple hammer drills, which increases the cost of use;

[0004] The above-mentioned existing technical solution has the following shortcomings: the technical solution replaces the drill body through the installation tube, installation groove, connecting strip, pull rod, insertion rod and reset spring during use, but the pull rod method adopted on both sides requires continuous pulling of the pull rods on both sides during installation, and blind matching of the holes on the connecting strip. If the staff holds other tools in their hands, there is inconvenience in installation, and there is a certain room for optimization. Therefore, it is necessary to design a quick-connect SDS handle connector to solve the above-mentioned problems. Utility Model Content

[0009] Preferably, a pull block is fixed on the outer side of the movable rod, and a hand groove is provided inside the pull block.

[0010] Preferably, the cross-section of the hand groove is arranged to be L-shaped, and the pull block and the mounting handle are in a movable connection relationship.

[0011] Preferably, a groove is formed on one side of the locking block away from the pressing surface, and a ball is movably connected inside the groove.

[0012] Preferably, a positioning groove is fixed on one side of the locking seat close to the mounting handle head, a positioning block is provided inside the mounting handle head on one side of the locking groove, and the positioning block is connected to the positioning groove.

[0013] Preferably, the size of the positioning block matches the size of the positioning groove, and the cross-sections of the positioning block and the positioning groove are both set to be rectangular.

[0014] Preferably, the diameter of the mounting block matches the diameter of the mounting groove, and the diameter of the locking seat matches the diameter of the mounting block.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the quick-connect SDS handle connector realizes the function of facilitating self-locking quick connection;

[0016] By providing a locking seat, the locking seat is placed in the mounting seat and continuously extended to the locking groove during the installation of the sleeve body. At this time, the locking seat contacts the locking block and continues to move forward under the action of the inclined pressure surface. The locking block is squeezed and moves outward at the same time and drives the connecting rod to move. The connecting rod drives the movable plate to move in the movable groove and squeezes the spring. When the locking seat fits the inner wall of the locking groove, the spring pushes the locking block to reset and snap into the end face of the locking seat, thus realizing the self-locking function of the sleeve body. The operation is simple and convenient, the installation difficulty is reduced, and the purpose of quick connection is achieved, so as to facilitate the replacement of sleeve bodies of different sizes and models.

[0017] By providing a pull block and a hand slot, the pull block is connected to the movable rod. When the sleeve body needs to be disassembled during use, the finger is placed in the hand slot, and the inner design of the hand slot is L-shaped, which fits the bending shape of the finger. At this time, the pull block is pulled outward to drive the locking block to separate from the end face of the locking seat, that is, the lock is cancelled, so that the sleeve body is easily replaced.

[0018] By providing the ball and the groove, when the locking seat presses the locking block during use, the locking block moves outward and drives the ball to contact and move with the inner wall of the locking groove. Under the action of the ball, the convenience and smoothness of the movement of the locking block are improved and the friction is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
