[0027] The guide protection unit 21 is arranged at the front end of the reciprocating saw body 1, and includes a roller mounting frame 211, and five guide protection rollers 212 are rotatably mounted inside the roller mounting frame 211;

[0028] The mounting unit 22 is disposed at the front end of the reciprocating saw body 1 and is used to facilitate the disassembly, assembly and maintenance between the reciprocating saw body 1 and the saw blade guide protection mechanism 2;

[0029] The adapting unit 23 is disposed at the front end of the mounting unit 22 and is used to enable the guide protection unit 21 to adapt to the guide of saw blades of different thicknesses.

[0030] The saw blade passes through the two guide protection units 21, and the surface of the guide protection roller 212 contacts the surface of the saw blade. When the saw blade reciprocates, the guide protection roller 212 rotates reciprocatingly, thereby achieving guiding protection for the saw blade, thereby preventing the saw blade from breaking at the root due to improper operation and affecting work efficiency, and at the same time avoiding the situation where the saw blade breaks at the root and causes cumbersome saw blade replacement.

[0031] In this embodiment, the mounting unit 22 includes a mounting plate 221 fixedly mounted thereon, four bolts 222 are rotatably mounted on the front side of the mounting plate 221 , and a connecting plate 223 is fixedly mounted on the top of the mounting plate 221 .

[0032] In this embodiment, the mounting plate 221 is fixedly mounted on the front end of the reciprocating saw body 1 by means of bolts 222 .

[0033] The mounting plate 221 is fixedly mounted on the front end of the reciprocating saw body 1 by means of bolts 222 , so that the saw blade guide protection mechanism 2 and the reciprocating saw body 1 can be disassembled and assembled, which facilitates the repair and maintenance of the saw blade guide protection mechanism 2 .

[0037] The user rotates the threaded column 235 by adjusting the knob 236, and the rotation of the threaded column 235 drives the linkage trapezoidal plate 237 to move up and down. The linkage trapezoidal plate 237 slides in the linkage slide groove 234 through the linkage sliders 238 installed on the left and right sides, thereby driving the two triangular sliders 233 to adapt to move towards or in the opposite directions in the cross slide groove 232, thereby driving the two guide protection units 21 set at the bottom of the two triangular sliders 233 to move synchronously, thereby realizing the guide protection for different saw blade thicknesses.

[0041] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0042] During operation, firstly, the mechanism is docked and installed with the front end of the reciprocating saw body 1 by means of the bolt 222, and then the saw blade is installed on the front end of the reciprocating saw body 1. At this time, the saw blade passes through the two guide protection units 21. Then, the user rotates the threaded column 235 by means of the adjusting knob 236.

The linkage trapezoidal plate 237 slides in the linkage slide groove 234 through the linkage sliders 238 installed on the left and right sides, thereby driving the two triangular sliders 233 to adapt to move toward or in the opposite direction in the cross slide groove 232, thereby driving the two guide protection units 21 arranged at the bottom of the two triangular sliders 233 to move synchronously, so that the guide protection roller 212 contacts the surface of the saw blade. Then, when the saw blade reciprocates, the guide protection roller 212 rotates reciprocatingly accordingly.
