Detailed Description

The invention will be further described with reference to specific embodiments.

As shown in fig. 1 to 5, a quick clamping device for a jigsaw comprises a reciprocating rod 1, wherein a clamp body 2 is mounted on the reciprocating rod 1, a saw blade groove 3 for mounting a saw blade is formed in the clamp body 2, an elastic sheet 4 is fixedly mounted on one side of the clamp body 2, an installation groove 5 is formed in the elastic sheet 4, the clamp body 2 is inserted into the installation groove 5, and a fixing plate 6 for fastening the saw blade is arranged in the installation groove 5; a mounting hole 7 is formed in the clamp body 2, a switch handle 8 is rotatably mounted in the mounting hole 7, and cams 9 used for pushing the elastic sheet 4 to move back and forth are formed on two sides of the switch handle 8.

This technical scheme's utility model can be under the condition with the help of no instrument very easily and dismouting fast, change the saw blade, the saw blade is difficult for dropping at fast-speed reciprocating motion and cutting process, the saw blade is to neutrality good, frictional force is little between each part, advantages such as long service life.

Preferably, a first limiting groove 10 and a second limiting groove 11 are formed between the clamp body 2 and the elastic sheet 4, and the first limiting groove 10 and the second limiting groove 11 are respectively clamped with a first limiting block 12 and a second limiting block 13 which are formed on a handle.

Preferably, a bevel 14 for guiding the saw blade into the blade groove 3 is formed at one side of the blade groove 3.

Preferably, the mounting groove 5 is opened in the middle of the clamp body 2.

Preferably, a recess 15 for abutting against a saw blade is provided in the clamp body 2.

Preferably, the reciprocating lever 1 is fixed with the clamp body 2 and the elastic piece 4 by a pin 16.

Preferably, the switch handle 8 comprises a left handle 17 and a right handle 18, the left handle 17 and the right handle 18 being connected by a screw 19.

The working principle is that when a user uses the quick clamping device to clamp the saw blade, the user firstly pulls the switch handle 8 downwards, at this time, the end with the minimum diameter of the cam 9 is abutted against the elastic sheet 4, the distance between the fixed plate 6 and one side of the clamp body 2 is at the maximum value, the user can place the saw blade in the saw blade groove 3, the upper end part of the saw blade is abutted against the groove 15, then the user pulls the switch handle 8 upwards, at this time, the end with the maximum diameter of the cam 9 is abutted against the elastic sheet 4, so that the distance between the fixed plate 6 and the clamp body 2 is reduced, the fixed plate 6 and the clamp plate 2 can fix the saw blade in the mounting groove 5, the utility model can be easily and quickly assembled and disassembled and replaced without any tool, the saw blade is not easy to drop in the high-speed reciprocating motion and cutting process, the saw blade has good centering performance and small friction among all parts, long service life and the like.
