Abstract
The utility model discloses a steel-chisel flat spade, and the flat spade comprises a spade handle and a spade head. The spade head is a steel-chisel spade. The bottom end of the spade handle is in threaded connection with the top end of the steel-chisel spade. The top end of the spade handle is provided with a circular protection disc through welding. The cross sectional area of the circular protection disc is three to five times as large as the cross sectional area of the spade handle. The central top part of the spade handle is provided with a handle which is perpendicular to the spade handle. The handle is sleeved by a sheath with elasticity. The flat spade provided by the utility model is convenient to operate, is long in service life, can effectively prevent a hand hammer from breaking away in a process of working in case of injury, and provides a reliable guarantee for the safety of a worker.
Description
Technical field
The utility model relates to conventional Work tool in a kind of electric operating process, particularly a kind of flat chisel.
Background technology
Flat chisel is one of Work tool often using in electric operating process, and normally used flat chisel comprises spade and shovel head, and spade and shovel head be structure as a whole, and sword is wider and thin conventionally for shovel head, convenient working.But band iron is in electric operating process, need to often root out harder material, therefore shovel head easily damages, and is integral type structure owing to shoveling head and spade, and therefore, in the time that shovel head is no longer sharp, whole flat chisel will cancel, and greatly reduces the useful life of whole flat chisel.In addition, for ease of gripping, the structure of spade is generally cylindrical structure, but in use, need to be with the top of hand hammer hammering spade, if operating personnel's improper use, hand hammer just, easily from the end slippage of spade, injures operating personnel's hand and arm by a crashing object, and fail safe is poor; Particularly, in the time of the larger angle operation of work difficulty, more easily make a fault, cannot guarantee the fail safe that operating personnel works.
Utility model content
The utility model technical issues that need to address are to provide a kind of handled easily, long service life and can effectively prevent hand hammer slippage and injure operating personnel's flat chisel by a crashing object in operation process.
For addressing the above problem, technical solution adopted in the utility model is:
Drill rod flat chisel, comprises spade and shovel head, and described shovel head is drill rod shovel, and the bottom of described spade is threaded with the top of drill rod shovel, and the top of spade is welded with circular protective plate, and the cross-sectional area of circular protective plate is 3 ~ 5 times of spade cross-sectional area.
Improvement of the present utility model is: the middle and upper part of described spade is welded with the handle perpendicular to spade.
Further improvement of the utility model is: on described handle, be set with the sheath with degree of tightness.
The beneficial effect that adopts technique scheme to produce is:
Spade of the present utility model and shovel head adopt the demountable structure being threaded, and are convenient to change shovel head in the time of shovel well damage.A shovel employing drill rod shovel, hardness is higher, not easy to wear, has improved useful life of the present utility model.The circular protective plate of the top welding of spade, can, in the time using the utility model, beat hammering protective plate with hand, increases contact area, has effectively prevented hand hammer slippage injury operating personnel in hammering process.The handle that spade middle and upper part arranges, is convenient to operating personnel hand-held, also can make operating personnel's hand be positioned at outside the direction of hand hammer hammering simultaneously, effectively protects operating personnel.The sheath being set with on handle, can in the winter time use time, prevent that operating personnel from holding for a long time ice-cold handle and causing hand frostbite; In the time of every day use, also can prevent in hand-held process because the palm of the hand has sweat to grip the generation that does not tightly cause slip phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1. spade, 2. shovel head, 3. protective plate, 4. handle, 5. sheath.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
