Abstract
The utility model discloses a kind of reciprocating saw, comprise reciprocating saw body, described reciprocating saw body comprises by motor-driven reciprocating lever, saw blade clamping device is fixed with in one end of described reciprocating lever, described saw blade clamping device comprises the gripper sleeve being fixedly installed on described reciprocating lever one end, saw blade holddown groove is all offered at described gripper sleeve vertical direction and horizontal direction, at described saw blade holddown groove two ends, there is steel ball seat, in described steel ball seat, steel ball is set, described gripper sleeve is sheathed on to be tightened in sleeve, the groove having and coordinate with described steel ball is tightened in sleeve described, saw blade inserts described groove.The utility model saw blade can the positive and negative insertion of in the vertical direction also can positive and negative insertion in the horizontal direction, therefore run into need to carry out from top to bottom to material the occasion that (or from left to right) cut time, only needing to carry out cutting operation according to holding rifle posture normally, using convenience very.
Description
Technical field
The utility model relates to field of power tools, more specifically, relates to a kind of reciprocating saw.
Background technology
Reciprocating saw is generally used for the polytype material of cutting.Jagged saw blade is cutting material when saw blade is reciprocal back and forth.Reciprocating saw is driven by motor.Rotating shaft or cam are generally used for making saw blade reciprocal.Usually, reciprocating saw is driven by the motor with rotating output shaft.Then the rotary motion produced by motor changes reciprocating motion into and moves to make saw blade.
Be smooth department in the You Chi side, side of reciprocating saw saw blade, the fixing structure of general saw blade is see structure disclosed in such as number of patent application " 200980124145.X " and number of patent application " 200910224938.0 ", and the side that saw blade is anodontia is inserted on clamping device that reciprocating saw body is arranged after guide wheel leads.Namely make saw blade have the side of tooth upward, therefore when fixing saw blade, saw blade also can only insert in the clamping device of reciprocating saw body to have one of tooth supine mode.Like this run into need to carry out from top to bottom to material the occasion that (or from left to right) cut time, can seem very inconvenient.Therefore be necessary to make improvements.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of reciprocating saw, and saw blade can load downwards straight up or load to from left to right.
The utility model is achieved through the following technical solutions: a kind of reciprocating saw, comprise reciprocating saw body, described reciprocating saw body comprises by motor-driven reciprocating lever, saw blade clamping device is fixed with in one end of described reciprocating lever, on described saw blade clamping device, clamping has saw blade, described saw blade clamping device comprises the gripper sleeve being fixedly installed on described reciprocating lever one end, saw blade holddown groove is all offered at described gripper sleeve vertical direction and horizontal direction, at described saw blade holddown groove two ends, there is steel ball seat, in described steel ball seat, steel ball is set, described gripper sleeve is sheathed on to be tightened in sleeve, the groove having and coordinate with described steel ball is tightened in sleeve described, when described saw blade inserts described saw blade holddown groove, described groove sidewall lean steel ball saw blade be fixed, when sleeve is tightened in rotation, described steel ball makes steel ball and saw blade stationary state remove away from the sidewall of groove.
In technique scheme, described gripper sleeve and tightening between sleeve is rotationally connected by torsion spring.
In technique scheme, have in described sleeve arranged outside of tightening the toggle be convenient to for tightening sleeve described in rotating.
The utility model has following beneficial effect: saw blade can the positive and negative insertion of in the vertical direction also can positive and negative insertion in the horizontal direction, therefore run into need to carry out from top to bottom to material the occasion that (or from left to right) cut time, only needing to carry out cutting operation according to holding rifle posture normally, using convenience very.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail: see Fig. 1 to Fig. 6, a kind of reciprocating saw, comprise reciprocating saw body 1, described reciprocating saw body 1 comprises by motor-driven reciprocating lever 2, be fixed with saw blade clamping device 3 in one end of described reciprocating lever 2, on described saw blade clamping device 3, clamping has saw blade 4.
Described saw blade clamping device 3 comprises the gripper sleeve 30 being fixedly installed on described reciprocating lever 2 one end, saw blade holddown groove 302 is all offered at described gripper sleeve 30 vertical direction and horizontal direction, at described saw blade holddown groove 302 two ends, there is steel ball seat 300, in described steel ball seat 300, steel ball 301 is set, described gripper sleeve 30 is sheathed on to be tightened in sleeve 31, the groove 310 having and coordinate with described steel ball 301 is tightened in sleeve 31 described, when described saw blade 4 inserts described saw blade holddown groove 302, the sidewall of described groove 310 leans steel ball 301 and saw blade 4 is fixed, when sleeve 31 is tightened in rotation, described steel ball 310 makes steel ball 301 and saw blade 4 stationary state remove away from the sidewall of groove 310.
When needing to insert saw blade 4, first rotate and tighten sleeve 31, make the sidewall of steel ball 301 principle groove 310, also namely steel ball 301 and groove 310 lean relation broken, now steel ball 301 can upper and lower displacement in steel ball seat 300, therefore now saw blade 4 can be inserted, after inserting saw blade 4, steel ball 301 is positioned at the concave position of saw blade both sides, now tightening sleeve 31 in rotation makes steel ball 301 lean the sidewall of groove 310, also namely steel ball is limited between the groove at two ends, and now saw blade 4 position is also firmly fixed.
Described gripper sleeve 30 and tightening between sleeve 31 is rotationally connected by torsion spring, i.e. gripper sleeve 30 and tighten sleeve 31 when being in physical slot, steel ball 301 leans the sidewall 9 (torsion spring provides and tightens the torsion that sleeve 31 is returned to this position) of groove 310.
The toggle 311 be convenient to for tightening sleeve 31 described in rotating is had in described sleeve 31 arranged outside of tightening.Be convenient to rotate easily tighten sleeve.
