Abstract
The utility model discloses a tube spanner. The utility model comprises an upper member, a lower member, and a connecting piece of the upper member and the lower member, wherein, the lower member comprises a sleeve cylinder for a handle, a handle, and an end part for a lower jaw opening. The sleeve cylinder for a handle is arranged at the outer part of the handle and is movably connected with the handle. The front part of the end part for a lower jaw opening is provided with a ratchet. The front end of the sleeve cylinder for a handle is provided with screw threads. The upper member is integration structure. The upper member is divided into an end part for an upper jaw opening and a grabbing part of the end part for an upper jaw opening. The inner side of the end part for an upper jaw opening is provided with ratchets which are arranged in vertical horizontal plane, which correspond to ratchets of the end part for a lower end part. The inner side surface of the grabbing part of the end part for an upper jaw opening is provided with screw threads which are engaged with the screw threads on the sleeve cylinder for a handle, etc. The utility model has the advantage of simple structure. The size of the jaw opening can be adjusted by directly adjusting the sleeve cylinder for a handle. Because the tube spanner is used, the utility model can be operated conveniently, and the labor can be saved. Thereby, the efficacy can be effectively improved.
Description
Technical field:
The utility model relates to a kind of spanner, especially relates to a kind of spanner of using on pipe specially, belongs to the hand-operated tools field.
Background technology:
Present bulldog wrench be spanner mostly with pipe between contact for point, simultaneously, again because present bulldog wrench is by regulate the middle nut of spanner with finger, regulate the size of the jaw of spanner, and finger is regulated strength deficiency after all, and also inconvenient, can not make fully that the size of jaw is just in time suitable, also occur thus skidding the shortcoming of bad use.
The utility model content:
It is a kind of simple in structure and can rotate by direct hand that the purpose of this utility model is to provide, and regulate jaw size, and the convenient a kind of bulldog wrench that uses.
The purpose of this utility model is implemented by following technical scheme: it includes the connector of upper component, lower member and upper component and lower member; Wherein said lower member includes handle sleeve and handle and lower jaw end, described handle sleeve places handle outer and handle work to be connected, described lower jaw end is connected as a single entity and places handle and handle barrel forward end for abnormity and described handle, and the front portion of described lower jaw end is provided with that the upright plane vertical with horizontal plane has an inclination angle and the ratchet arranged; Behind described lower jaw end, and the front end of described handle sleeve is provided with screw thread; Described upper component is structure as a whole, be divided into upper jaw end and upper jaw end portion, and described upper jaw end perpendicular to the upper jaw end portion, it is corresponding with the ratchet of lower jaw end that inboard, described upper jaw end is provided with the ratchet that is the vertical level arrangement, and the medial surface portion of described upper jaw end is provided with the screw-threaded engagement on screw thread and the described handle sleeve; And the rear portion that described connector is connected described lower jaw end is the threaded portion on the described handle sleeve, connects upper component and described lower member.
Inboard in described connector upper end, be described upper jaw end portion top, put and leave certain space.
Left side, lower end at described connector opens a gap.Its objective is in order to prevent the rotation of handle.
Between described handle and described handle sleeve, can take screw to connect, or other connected mode.It is in order to prevent that described handle from skidding off from described handle sleeve.
Head end blocks mutually on the left of stretching out an eaves and described handle sleeve in termination, described connector left side, and describedly stretches out eaves and described connector is in aggregates.It is in order to prevent that connector from skidding off from the right side.
Elastic steel sheet one end position and described connector top, fixedly connected with it, the other end position of described elastic steel sheet and described upper jaw end portion top.
The ratchet of described lower jaw end is corresponding with the ratchet of described upper jaw end.The making height in left side, described lower jaw end can not influence horizontally slipping and operate as normal of upper component.
The utility model has the advantages that: simple in structure and can pass through direct regulating handle sleeve, and regulate jaw size, and adopt this bulldog wrench, it is more convenient, laborsaving to operate, thereby can effectively improve effect.
