Abstract
The invention discloses a simple hand-operated puncher and relates to the technical field of portable drilling machines. The simple hand-operated puncher comprises a drill rod and a drill bit and is characterized in that the middle of the drill rod is provided with a U-shaped rocking arm; the rocking arm is provided with a sleeve; one end of the drill rod is provided with a chuck, the drill bit is fixedly connected with the drill rod by virtue of the chuck; and the other end of the drill rod is provided with a grab handle. The simple hand-operated puncher is simple in structure, convenient to carry and use, and convenient in bit replacement, especially can be used for conveniently and easily punching and broaching an ammeter box and a wall under the condition of no power supply in the power construction process, is rapid and accurate, and can be used for greatly shortening the installation and fixation time of the ammeter box and improving the overall working efficiency; and the chuck is convenient to use, and the drill bit can be firmly chucked.
Description
Technical field
The present invention relates to the portable drill technical field, especially a kind of ammeter box is installed and is used card punch.
Background technology
In new electrification of the countryside village transformation process, the Installation of New Type ammeter box is one of emphasis in the Overall Reconstruction process, but the rural area wall quality is uneven, brick body slit height is intricate, install for reaching standardization, guarantee that same plane interior wall body surface case height is consistent, therefore must carry out appropriateness punching reaming to body of wall.
Electric drill is the electric tools of normal use of people, but the drill bit of electric drill is longer, the large quality of volume is heavy, and inconvenient hole at narrow and small particularly reverse backing, general electric drill is not accurate because workman's direction is grasped in boring, deflects easily the quality of impact boring, and may affect the position that wall section causes more greatly whole round in the relatively poor situation of rural area wall quality needs change, not only wasting manpower and material resources but also can delay the duration.Usually power issue is difficult to resolve certainly in the rural power work progress, so the use of electric drill is restricted.
Drill chuck head commonly used all is to tighten with the key reinforcing drill bit to be clamped fixing, if coupling mechanism force is inadequate, then drill bit rotates in drill chuck head, and drill chuck head easily frays.
Summary of the invention
The technical problem to be solved in the present invention provides the hand card punch of a kind of plain type, the present invention is simple in structure, portably use conveniently, be convenient to more bit change, can make things convenient in the non-transformer situation in the power construction process particularly that his-and-hers watches case and body of wall punch easily, reaming, accurately quick, greatly shorten the time that installs and fixes of ammeter box and improved whole work efficiency.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the hand card punch of a kind of plain type comprises drilling rod and drill bit; The centre of drilling rod is provided with the U-shaped rocking arm, and rocking arm is provided with sleeve pipe, and an end of drilling rod is provided with dop, and drill bit is fixedly connected with drilling rod by dop, and the other end of drilling rod is provided with lever.
The preferred structure of described dop is: comprise claw, housing, main shaft, claw is conical surface setting along main shaft, and claw and main shaft are threaded connection, between claw and the housing for closely being slidingly connected, bonnet is set behind the housing, and it connects as one, and between bonnet and the main shaft steel ball is set; Claw is the three-pawl type structure; Steel ball is arranged in the rectangular main shaft groove.
Be connected for rotational structure between preferred lever and drilling rod.Lever can be for cylindric, and drilling rod can be fixedly connected with the center of cylindric lever.
Preferred lever periphery is provided with rubber sleeve.
Drill bit is provided with chip area.
The beneficial effect that adopts technique scheme to produce is: the present invention is simple in structure, portably use conveniently, be convenient to more bit change, can make things convenient in the non-transformer situation in the power construction process particularly that his-and-hers watches case and body of wall punch easily, reaming, accurately quick, greatly shorten the time that installs and fixes of ammeter box and improved whole work efficiency.Dop of the present invention can be realized quick-detachment and drill bit is installed that drill bit can firmly be tightened.Wear drill bit also.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of dop;
Fig. 3 is the structural representation of drill bit;
1 is drilling rod, and 2 is drill bit, and 3 is the U-shaped rocking arm, and 4 is lever, and 5 is sleeve pipe, and 6 is chip area, and 7 is dop, and 8 is claw, and 9 is housing, and 10 is steel ball, and 11 is bonnet, and 12 is main shaft.
The specific embodiment
Embodiment 1
This portable manual card punch comprises drilling rod 1 and drill bit 2; The centre of drilling rod 1 is provided with U-shaped rocking arm 3, and an end of drilling rod 1 is provided with drill bit 2, and the other end of drilling rod 1 is provided with lever 4;
Rocking arm 3 is provided with sleeve pipe 5;
Lever 4 is cylindric, and drilling rod 1 is fixedly connected with the center of cylindric lever 4;
Lever 4 peripheries are provided with rubber sleeve;
Drill bit 2 is provided with chip area 6;
One end of drilling rod 1 is provided with dop 7, and drill bit 2 is fixedly connected with drilling rod 1 by dop 7, and dop can use the conventional dop in this area.
Dop 7 comprises claw 8, housing 9, main shaft 12, and claw 8 is conical surface setting along main shaft, and claw 8 is threaded connection with main shaft 12, between claw 8 and the housing 9 for closely being slidingly connected, bonnet 11 is set behind the housing 9, and housing and bonnet connect as one, and between bonnet 11 and the main shaft 12 steel ball 10 are set; Claw 8 is the three-pawl type structure; Steel ball 10 is arranged in rectangular main shaft 12 grooves; Steel ball 10 is parallel with main shaft 12 groove inner faces with the contact-making surface between the bonnet 11.During use drill chuck head is contained on the drilling rod, gets final product loading onto drill bit in the claw again.When drill bit contact workpiece, then produce drilling torsion, under the effect of drilling torsion, claw moves upward under the threaded function of main shaft, dop auto lock then, torsion is larger, lock tighter.When the drilling end-of-job, owing to be provided with steel ball between main shaft and the housing, be rolling friction between it, coefficient of friction is very little, therefore is easy to unclamp, and only needs oppositely to twist shell with hand, drive claw and spindle thread and oppositely unclamp, can realize fast loading and unloading and more bit change.
Little being convenient for carrying of card punch volume of the present invention, cylindric lever can well coincide with palm, and rubber sleeve can be placed the wearing and tearing of adversary's carpel skin in the long-term use procedure; Chip area can in time be discharged the wood chip in the boring procedure; Drill bit is fixedly connected with drilling rod by dop, drill bit can be disassembled when not using or in the transportation, and workman or other utensil prevent from damaging; When using card punch boring, the sleeve friction on drilling rod and the U-shaped rocking handle is avoided direct friction skin.
When using card punch of the present invention drill bit is installed on the dop and gets final product, can the his-and-hers watches case and body of wall punches easily, reaming, and firm, convenient and swift.Originally the his-and-hers watches case is fixed about needs 10～15 minutes, only needs 5～6 minutes now, has promoted whole work efficiency.Be particularly suitable for ammeter box usefulness is installed.
