Abstract
A spanner is composed of a handle and a clamping mouth consisting of a fixed jaw and a movable jaw. It features that said handle has an internal cavity with cover plate, in said cavity there are a fixed toothed bar, a drive toothed bar, a moving toothed bar connected to said movable jaw, a slide gear, two drive gears, and a regulating gear, and one or two push slide blocks linked with the axle of slide gear are arranged on the surface of handle.
Description
One, technical field
The invention discloses a kind of instrument, particularly a kind of spanner commonly used belongs to the instrument design field.
Two, background technology
Existing spanner causes it in use all to exist operation dumb mostly because its structural design gets irrationality, easily skids, and safety coefficient is low, and the inferior deficiency of inefficiency uses limitation bigger.
Three, summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and disclose a kind of easy to operate, high efficiency, safe and reliable spanner.
For achieving the above object, the technical solution used in the present invention is: a kind of spanner, comprise handle and front end thereof by mobile latch and fixedly latch constitute the spanner bayonet socket, its special character is, in handle, be provided with the vallecular cavity of peripheral hardware cover plate, side in the vallecular cavity is provided with stationary rack, opposite side on the other side is provided with the driving rack that can move forward and backward along the vallecular cavity wall, end near the spanner bayonet socket in the vallecular cavity is provided with the mobile rack of fixedlying connected with mobile latch, a balladeur train is housed in the vallecular cavity, two travelling gears, one or several intermeshing adjusting gears are housed between two travelling gears, balladeur train is installed between stationary rack and the driving rack and with the two and is meshed simultaneously, travelling gear near bayonet socket is meshed with mobile rack, and another travelling gear is meshed with driving rack; On handle, be provided with the promotion slide block that one or two is connected with the slide teeth wheel shaft.
A position limited gear that is meshed with it respectively is equipped with at the two ends of above-mentioned mobile rack.
The good effect that compared with the prior art the present invention has is, the switch sensitivity of spanner is easy to operate, non-slip during use, safe and reliable, and high efficiency is applied widely.
Four, description of drawings
Fig. 1 is an internal structure schematic diagram of the present invention.
Fig. 2 is a front view of the present invention.
Fig. 3 is a rearview of the present invention.
Fig. 4 is a side view of the present invention.
Five, the specific embodiment
For understanding the present invention better, it is done further detailed elaboration below in conjunction with drawings and Examples.
With reference to Fig. 1-Fig. 4, spanner of the present invention mainly be by handle 1 and front end thereof by mobile latch 2 and fixedly latch 3 constitute spanner bayonet socket 12 constitute, in handle 1, be provided with the vallecular cavity 13 of peripheral hardware cover plate 11, side in the vallecular cavity 13 is provided with stationary rack 4, opposite side on the other side is provided with the driving rack 6 that can move forward and backward along the vallecular cavity wall, end near the spanner bayonet socket in the vallecular cavity is provided with the mobile rack 14 of fixedlying connected with mobile latch 2, balladeur train 5 is housed in the vallecular cavity 13, travelling gear 7 and 9, two intermeshing adjusting gears 8 are housed between travelling gear 7 and the travelling gear 9,8 ', balladeur train 5 is installed between stationary rack 4 and the driving rack 6 and with the two and is meshed simultaneously, travelling gear 7 is meshed with driving rack 6, travelling gear 9 is meshed with mobile rack 14, at the two ends of mobile rack 14 position limited gear that is meshed with it 10 is housed respectively, 10 '; On the upper and lower surface of handle 1, respectively be provided with a promotion slide block 15 that is connected with the slide teeth wheel shaft.
According to actual instructions for use, the installation site of adjustable solidating fixed rack, balladeur train and driving rack is to satisfy user demand.
During use, with hand propelled slide block 15, balladeur train 5 drives driving rack 6 and moves, driving rack 6 drives the travelling gear 7 that is meshed with it and moves, travelling gear 7 so drive the adjusting gear 8,8 that is meshing with each other ' and travelling gear 9 rotate, wear moving gear 9 and drive the mobile rack 14 that is engaged with and move, thereby the mobile latch 2 of fixedlying connected with mobile rack is moved, realize the switch of spanner bayonet socket 12.
