Description
Technical Field
The utility model belongs to the technical field of electric tool, refer in particular to a chain saw chain drive counting mechanism.
Background
A chain saw is a hand saw powered by a gasoline engine, is mainly used for lumbering and building materials, and has the working principle that the transverse movement of staggered L-shaped blades on a saw chain is used for shearing. The chain saw is a machine which is often seen in green gardens, mainly takes gasoline as power, and takes a saw chain as a handheld machine. The chain saw is widely applied to landscaping in China. The chain saw is mainly used for cutting branches, felling trees and the like.
The chain of chain saw is driven its rotation by driving gear and driven gear, can't count the number of turns of rotation of driving gear among the current chain saw, counts the driving gear of chain saw and has more extensive practical meaning, for example selects rated time to test its number of turns of rotation, can obtain its operating speed, can help the operator to know the performance of chain saw.
SUMMERY OF THE UTILITY MODEL

Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic structural diagram of the counting mechanism part of the present invention.
Detailed Description
The invention will be further described with reference to specific embodiments.
As shown in fig. 1-2, a chain transmission counting mechanism of a chain saw comprises a chain saw body 1, a motor 2 for driving a saw blade to rotate is arranged in the chain saw body 1, a motor shaft 3 is arranged in the motor 2, one end of the motor shaft 3 is arranged outside the chain saw body 1, a first gear 4 is sleeved at the outer end of the motor shaft 3, a second gear 5 is meshed at one side of the first gear 4, an inclined surface 6 is arranged on the upper end surface of the second gear 5, a jacking device 7 is abutted on the inclined surface 6, the jacking device 7 comprises a fixed seat 8 fixedly arranged on one side of the chain saw body 1, a telescopic rod 9 is arranged in the fixed seat 8 in a telescopic way, the upper end of the telescopic rod 9 is provided with a mounting seat 10, a pulley 11 is rotatably arranged in the mounting seat 10, the pulley 11 is abutted against the inclined surface 6, an abutting block 12 is arranged on the mounting seat 10, and the upper end of the abutting block 12 is abutted against a counter 13.
This technical scheme can drive the rotation of second gear 5 through first gear 4 when the chain saw uses, and at this moment inclined plane 6 above first gear 4 all can drive pulley 1 to peak once when every turns the round, and its butt piece 12 can butt counter 13 in the peak, can once press counter 13, realizes once counting every rotation round, this simple structure, and is stable, and low in production cost.
Preferably, a fixing rod 14 is arranged on one side of the chain saw body 1, and a second gear 5 is rotatably sleeved on the fixing rod 14.
Preferably, the chain saw body 1 is provided with a mounting frame 15, and the counter 13 is detachably arranged between the mounting frames 15. The removable arrangement of the counter 13 enables the user to replace the counter 13.
Preferably, the two ends of the counter 13 are provided with buckles 16, and the buckles 16 are clamped with clamping grooves formed in the two inner walls of the mounting frame 15. The counter 13 can be prevented from falling off when the abutting block 12 abuts against the counter 13 by the cooperation of the catch 16 and the card slot.
The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
