Abstract

The utility model designs a connecting device for a tool handle. The handle is divided into a first rod section, a second rod section, a pressing handle and an annular buckle body, wherein the first rod section and the second rod section are mutually connected. The front end of the first rod section is connected with a tool body, the back end of the first rod section is provided with a sleeve extending along an axial direction, and a clipping tenon is convexly arranged on the outer wall of the sleeve. The front end of the second rod section is convexly provided with a connector along a radial direction, and a tenon part which can be just plugged in the sleeve is arranged along the axial direction. One end of the pressing handle is pivoted on the connector, and one end of the annular buckle body is pivoted to the middle part of the pressing handle. When the pressing handle is downward pressed clockwise to be appressed to the second rod section, the annular buckle body is in a tension state and a force moment which can make the pressing handle rotate clockwise is generated simultaneously. The pressing handle is appressed to the second rod section, and the first and the second rod sections are firmly connected.

Description

A kind of jockey of handle for tool

[technical field]

The utility model relates to a kind of jockey of handle for tool.

[background technology]

With reference to figure 1, present employed instrument, its handle 21 generally is by welding or bonding being fixed together with being connected of tool body 22 (i.e. Chan shovel head), handle 21 is difficult to dismounting with tool body 22 and separates, when tool body or handle damage, difficult the replacing; And when carrying out some work, work as the gardening gardens, often need to use the instrument of different size or kind to finish the work, as shovel, rake and claw etc., because handle for tool is that one is connected with tool body, it is very inconvenient to carry more instrument, therefore is necessary the connected mode of present handle for tool and tool body is improved.

[utility model content]

The purpose of this utility model is to provide a kind of jockey of the handle for tool that can conveniently realize the dismounting of handle and be connected and installed.

The jockey of a kind of handle for tool of the utility model design, it is characterized in that: this handle is divided into the interconnective first bar section and the second bar section, the front end of the described first bar section is connected with tool body, the rear end then is provided with a sleeve that extends vertically, and the outer wall of sleeve convexes with a trip; The front end edge of the described second bar section radially convexes with a connector, is extended with a tenon portion that just inserts in the sleeve vertically; A handle, the one end is articulated on the connector; An annular button, the one end is articulated in the middle part of handle, makes when pressuring press handle is adjacent to the second bar section down clockwise, and annular button is in tension, produces the moment that handle is clockwise rotated simultaneously.

Further improvement as such scheme is characterized in that: the sleeve-port periphery has breach, the then corresponding protuberance that can embed breach that is provided with of tenon portion.

One, the utility model can be easy for installation and removal

When the utility model is installed, earlier the tenon portion alignment sleeve of the second bar section front end is inserted, one end of annular button is snapped on the trip, descend pressuring press handle to make handle be adjacent to the second bar section clockwise, make annular button be in tension and the tension of the first bar section and the second bar section.In the process of rotating handle, the annular button produces reaction force to handle, tie point with button and trip, handle at pivoting point on the connector and button 3 of pivoting points on handle whether in a straight line as critical line, clockwise direction rotates handle, button produces the moment that handle is clockwise rotated, make handle be close to the second bar section, this moment, button was in the state of tension trip and handle, realized the firm connection of the first and second bar sections, and because the first bar section of tool body and handle is an one, being connected of the first bar section of handle and the second bar section promptly realized being connected of tool body and whole handle; Counterclockwise rotate handle, button then produces the moment that handle is clockwise rotated, and button is in the state of getting loose on trip, and can remove the second bar section and the first bar section branch this moment.

Two, use instrument of the present utility model can be convenient for carrying and save cost of transportation

Because the first bar section and the second bar section can be easy for installation and removal,, the second bar Duan Keyu of the handle of a basic utility model connects the second bar section that only need carry a handle when carrying a plurality of tool body when going out so carrying the first bar section of different tool bodies.And in transportation, the first bar section of handle and the second bar section can be placed apart and packing, saved cost of transportation and space.

Three, the utlity model has stability and operability preferably

Because the tenon portion of the second bar section of handle is taper, head is less, and barrel bore then is the horn-like of correspondence, make the easily alignment sleeve insertion of tenon portion, and both walls can cooperate closely; Because the sleeve-port periphery has breach, the then corresponding protuberance that can embed breach that is provided with of tenon portion, along with tenon portion inserts sleeve, this protuberance embeds in breach second bar section location, prevents that the second bar section from rotating in sleeve.

[specific embodiment]

Referring to figs. 2 to Figure 11, the utility model is to implement like this: it is a kind of jockey that shovels handle, this handle 1 is divided into the interconnective first bar section 2 and the second bar section 3, the front end of the first bar section 2 is connected with tool body 4, the rear end then is provided with an extension vertically and inner chamber is trumpet-shaped sleeve 21, the outer wall of this sleeve 21 convexes with a trip 211, and the sleeve-port periphery then has breach 212.The front end edge of the second bar section 3 radially is concaved with a cannelure 31, is extended with a tenon portion 32 that just inserts in the sleeve vertically, and this tenon portion is taper, and head is less.A radial opening and radially convex with the annular cover 5 of connector 51, be embedded in the cannelure 31 along tenon portion 32, and by a screw opening is locked, the annular cover is fixed on the second bar section, and should convexes with the protuberance 52 that can embed breach 212 vertically by the annular cover; A handle 6, one end have the axis hole 61 that is articulated on the connector 51, and the both sides of handle have one along the radius of gyration of pivot different preceding duct 62 and duct 63, back; An annular button 7 that forms by the elastic metallic yarn bending, for making button 7 obtain retractility preferably, its side appearance slightly is bending, these button 7 one ends are articulated in the middle part of handle, the other end of this button 7 is made up of two ends wiry, this two ends is surrounds on the preceding duct 62 and duct 63, back that shape one in front and one in back is hubbed on handle respectively, and when making down pressuring press handle be adjacent to the second bar section, annular button is in tension.

In the process of rotating handle, 7 pairs of handles of annular button 6 produce reaction force, with the tie point of button and trip, handle at pivoting point on the connector and button 3 of pivoting points on handle whether in a straight line as critical line, clockwise direction rotates handle, button 7 produces the moment that handle 6 is clockwise rotated, make handle 6 be close to the second bar section 3, this moment, button 7 was in the state of tension trip and handle, had realized the firm connection of the first and second bar sections.Because tool body 4 is an one with the first bar section 2 of handle, being connected promptly of the first bar section 2 of handle and the second bar section 3 realized being connected of tool body and whole handle; With reference to figure 8, Fig. 9 and Figure 11, counterclockwise rotate handle, button then produces the moment that handle is clockwise rotated, and button is in the state of getting loose on trip, and can remove the second bar section and the first bar section branch this moment.
